Long Live EINA
I have recently seen my 61st birthday come round which has special meaning in the Chinese calendar of coming back to the name of the year one was born. 1999 is the year of earth & rabbit as 1939 was. Sixty years have past since I was born of which I spent more than thirty years deeply involved in the research and education of electrical insulation materials and technology. In retrospect the electrical engineering developed monstrously into electronics, communication engineering, computer science and technology during my career years.
Imagine an international conference thirty years ago. Announcements, registration, program brochure and hotel reservations for the conference were all done through postal mailings or telephone callings. They have all been replaced by the Internet home page system. If you are not familiarized with a computer approach, you will miss the conference. If you are, you can update your conference information by browsing on your PC panel. This is the outcome of the computer and communication technology, and we could hold 1998 International Symposium on Electrical Insulating Materials (ISEIM'98) in Toyohashi, Japan in September 1998.
I understand that although the electrical insulation plays seemingly very passive role of sustaining voltage, it performs the role of power or signal transportation just as current carrying conductors. Since electricity is the sole and unique source of energy in the electronic, communication and computerized world, it is satisfying to know electrical insulation is indispensable wherever electricity is working. Therefore, gLong live EINA!h Human beings depend more and more on electricity in the coming new century and millennium if we can successfully clear the Y2K hurdle originated from the lack of our imagination at the birth of computer age.
Even in the field of electrical insulating materials and technology the application of computer is the main concern. The fingerprinting of partial discharge is only possible by computers. The monitoring a performance of apparatus and the insulation diagnosis can be effectively carried out by computers. At the same time the reliability of versatile computers is guaranteed by the electronic insulation technology. The computer technology is changing the world in unpredictable pace. Whether it contributes to our prosperity and amenity heavily depends on the imagination and cleverness of human beings.

Society Activity in Transition
@After world war II, Japan has
achieved miraculous economic progress.
Especially, during this last ten years and over, we saw a remarkable
growth in the Japanese economy, bringing it to a size comparable with that of
Western countries and even dragging the world economy along with it. What laid
the foundation for all these economic progress are the gigantic semiconductor
industry and the information, electric and electronics industries including the
computer industry which are basically supported by the highly reliable electric
power system. However, for the
past few years with the future of the Japanese economy becoming more
unpredictable, the high level of economic growth has reached its end and the
Japanese economic environment has become really tough. Moreover, the neighboring Southeast
Asian countries have been gradually developing and are now competing with Japan
in the areas of hardware intdustries as steel, raw materials, machine parts,
and so on. Considering the advent
of Japan's advanced info-tech society and it's aging population together with
various environmental problems such as global warming, as far as our country's
industrial structure is concerned, a shift from the material-intensive type of
industry to a knowledge-intensive type of industry is inevitable.
@
As for the electric power industry which serves as the cornerstone of all
industries, while ensuring system reliability there is also the requirement to
cut on cost at the same time that from the viewpoint of the planet earth being
likened to spaceship, consideration towards the earth's environment has become
a matter of topmost concern. This has already started a kind of new quickening,
calling for structural reform in the industrial field and a change of direction
of scientific societies' various committee activities and also of academic
institutions' educational and research activities. These reforms take the deregulation in the electric power
industry and the various reforms adopted by universities aimed at achieving Center
of Excellence status. In both the industrial field and the academe, the idea of
competition has been introduced for the purpose of revitalizing both industry
and academe.
@ The Japan Institute of Electrical
Engineering has five Societies A to E.
The Technical Committee of Dielectrics and Electrical Engineering that
publishes this newsletter belongs to Society A (Fundamentals and Material
Society) which is composed of 8 technical committees, namely Research and
Education, Electrical Discharges, Light Application and Visual Science,
Instrumentation and Measurement, Dielectric and Insulation, Metal and Ceramics,
Magnetics, and History of Electrical Engineering. In order to catch up with
changes in these fields, four new technical committees designed to actively
contribute to the Society's future were inaugurated. These are the Technical Committee on Electromagnetic Theory,
Technical Committee on Plasma Science and Technology, Technical Committee on
Electromagnetic Compatibility, Technical Committee on Pulsed Electromagnetic
Energy. Of the four newly
inaugurated committees three are closely related to Electrical Insulation and
Discharges, namely Plasma Science, Electromagnetic Compatibility, and Pulsed
Electromagnetic Energy. The
respective chairmen of these committees will do us a favor of writing about
their committee on this issue.

MEMORIAL
ADDRESS
Prof. T. Mizutani
Great
Contributions of Late Prof. M. IEDA
It is very sad
to report that Professor Masayuki Ieda suddenly passed away on March 3, 1999 by
pneumonia at the age of 73. He was
a great worldwide leader in the field of Electrical Insulation and he made great
contributions to bridge between Japan and International world (Asia, Europe and
America) and also between Material Sciences and Technologies.
His
main research achievements were many pioneering works in the development of
polymeric insulating materials and their applications to high voltage power apparatus
and cables, especially in 275 kV and 500 kV crosslinked polyethylene power
cables. As early as 1950, he
realized the potential applications of synthetic polymers as new insulating
materials for electric power apparatus and cables. He has authored more than
400 papers and about 15 books. Many students who received their training in
Prof. Ieda's laboratory became researchers and leaders in Japanese industries
or university professors. Prof.
Ieda's scientific accomplishments earned him a worldwide reputation. He delivered the Whitehead Memorial
Lecture at CEIDP in 1986 and received IEEE Lamme Medal in 1993. He received many other awards such as
the Electric Power Award of IEE Japan in 1980, the Outstanding Contributions
Award of IEE Japan in 1993 and the CIGRE Distinguished Member Award in 1995.
Prof. Ieda had
served as Board Member of many international conferences (such as CEIDP,
ICPADM, ICSD, ICDL, ISE, ISH and so on), chairing sessions and serving as a
spokesman from Asia and Japan. He
was General Chairman of the 3rd International Conference on Properties and
Applications of Dielectric Materials (ICPADM) in 1991 in Tokyo. He was also the Japanese representative
to CIGRE SC-15 (Materials for Electrotechnology) from 1985 to 1990.
He was Chairman of IEEJ Technical
Committee of Electrical Insulating Materials from 1976 to 1983, Vice President
of IEE Japan from 1985 to 1987 and President from 1991 to 1992. He was also Member of the Science
Council of Japan from 1985 to 1994.
He devoted himself to the development of electrical insulation
technologies and electrical engineering and also to the development of Science
and Technology in Japan..
Prof. Ieda was
born on Oct. 8, 1925 in Tokyo, Japan. He received the Bachelor's Degree in
Electrical Engineering in 1949 and the Ph. D in Engineering in 1964 from Nagoya
University, where he joined the faculty as Research Associate, later becoming
Associate Professor and Professor of Electrical Engineering. He spent two years, 1964-66, as a
postdoctoral fellow at Cornell University with Prof. P. Debye (a Nobel prize
winner). From 1986 to 1989 he was
Dean of the School of Engineering, Nagoya University, and he retired from
Nagoya University in 1989. He was
Professor Emeritus at Nagoya and Professor at Aichi Institute of Technology
since 1989
Prof. Iedafs
Farewell party was held at Nagoya Garden Palace Hotel on May 7, 1999, and about
500 persons gathered there to remember and thank him. Professor Ieda will be remembered by the scientific and
engineering community not only as an eminent scholar but also as a great
leader.

This Technical Committee (TC-DEI) was set up in 1979 succeeding the Permanent Committee on Electrical Insulating Materials at the reorganization of IEEJ. The activities of the Committee are covering mainly solid and composite dielectric and insulating materials and technology.
The primary activity of TC-DEI
is the annual Symposium of Electrical and Electronic Insulating Materials and
Applications in Systems, formerly called Symposium on Electrical Insulating
Materials. In 1997 the 29th
Symposium was held at Central Electric Club in Osaka on Sept. 30 and Oct.
1. Sixty-eight papers were
presented including the invited paper of Prof. E. Gockenbach of Universität Hannover, Germany. The 30th Symposium in 1998 was jointly
held with IEEE DEIS, Chinese Electrotechnical Society and Korean IEE in the
style of International Symposium (ISEIM-98) in Toyohashi from Sept. 28 to 30,
1998, and ended very successfully.
The numbers of papers and participants of ISEIM-98 respectively exceeded
200 and 180, beyond our expectation.
The 31st Symposium will be held at the TEPCO R & D Center in
Yokohama on November 16 and 17, 1999.
The next ISEIM will be held jointly with the 34th Symposium in 2002,
although its details have not been determined.
The TC-DEI organizes the
Seminar for Young Researchers of Dielectrics and Electrical Insulation every
two years. Its 27th meeting will
be held on November 19 and 20, 1999.
The TC-DEI currently runs seven Investigating Committees (IC) which organize Technical Meetings (105 papers in 1998) and one Cooperative Research Committee (CRC) which edits and publishes this EINA.

The Technical Committee on Plasma Science and
Technology (TC-PST) was founded in April 1999. This committee has the basis on the plasma
reseacher's society that has organized Plasma Research Symposia several times
every year since about 30 years ago.
The field of activity of this committee includes researches and
investigations of various plasmas in terms of plasma physical parameters as
density, temperature and ionization degree, and application fields as nuclear
fusion, plasma processing, and plasma chemistry.
The major activity of this committee is to succeed to
organize the Plasma Research Symposia. Since April 1999, three symposia were
held; in June at Osaka University, in September at Waseda University in Tokyo
and also in September at National Institute of Fusion Science in Toki City followed
by a study tour to the Large Helical Device (LHD) for fusion research. Once or
twice every two years, symposium will be held outside Japan as Korea and Taiwan
in collaboration with their domestic societies related to plasma science and
technology. At each symposium, about 20 to 30 presentations are made.
Presentations by young researchers in bachelor course and master course are
strongly encouraged and appreciated.
TC-PST currently runs one investigation committee,
and, a few new will be set up in future.

This new Technical
Committee (TC-EMC) started in April 1999 in the Fundamentals and Materials
Society (A-Society), the Institute of Electrical Engineers of Japan (IEE,
Japan). It followed the breaking-up
of the former Technical Committee on Applied Physics of Electricity (APE) into
four technical committees.
Our modern life today
is full of electromagnetic fields due to naturally-origined sources like
lightning as well as artificial ones in almost all kinds of frequency. These sources make complex
electromagnetic environments which usually give necessary benefits to and
sometimes on the other hand interfere with every aspect of our life. The EMC (electromagnetic compatibility)
issues are increasing their importance more and more with the recent
development of the electricity-dependent life.
The issues have
already been actively studied, for example, by a Research Committee (EMCJ) in
the Institute of Electronics, Information and Communication Engineers (IEICE),
Japan. The establishment of the
TC-EMC in the IEE, Japan is based on the increasing significance of the field
together with the fact that both sources and influences in the EMC issues have a
close relation with electrical engineers.
The TC-EMC deals with the following items as the scope of its
investigation activities.
a) Generating sources of electromagnetic interferences,
related to high voltage, static elect-rification, high current, electrical
discharge, power electronics devices, and so on.
b) Actual situations of electromagnetic interferences
c) Measuring techniques in EMC
d) Countermeasures against electromagnetic interferences
e) Domestic and foreign standards related with EMC
The TC-EMC plans to start two investigation committees in the fiscal year 1999 up to March 2000. One of them, Investigation Committee on Lightning Damages in the Highly Information-Oriented Society, was already approved to begin its activity in January 2000. The chairperson is Dr. S. Yokoyama in the Central Research Institute of Electric Power Industry. It intends to investigate various aspects concerning damages caused by lightning with the term of about two years until March 2002. The investigation items are to cover, for example, countermeasures in low-voltage networks for electronics and communication, related standards abroad, techniques for analyzing lightning damages, and cost estimations.
Technical
Committee on Pulsed Electromagnetic Energy (PEE)
Chairperson Kiyoshi Yatsui (Nagaoka
university of Technology)
Vice Chairpersion Shozo Ishii (Tokyo Institute of Technology)
Secretaries Kazuhiko Horioka
(Tokyo Institute of Technology)
Assistant Secretary Weihua Jiang (Nagaoka university of Technology)
The Technical Committee on Pulsed Electromagnetic
Energy (TC-PEE) has been set up just recently, on July, 1999, to offer the
opportunities for the members of IEE of Japan in the fields of the R & D on
pulsed power technology and associated applications.
It has been successfully available to achieve
extremely high energy density state by the pulsed power technology, for a very
short time duration, though. To study
it from various points of views is very important not only from a physical aspect,
but also from a lot of applications. Such an extreme state achieved is closely correlated
with many applications because it involves extremely high temperature, high
pressure, high electric filed, high density, high magnetic field strength, and
so on. In this technical
committee, the main themes concerned are ¬ the development of pulsed
power technology, the achievement of extremely
high energy density by being transferred to many kinds of beams, and ® the associated
applications. Although there has
been growing number of scientists in this particular fields of interests, there
have been no systematic activities in Japan. The establishment of this technical committee will be very
useful in various aspects not only from electrical engineering but also from
other related engineering and technologies. Regularly, four Technical Committee meeting will be
held per year.
As of 1999, there is one investigation committee in
TC-PEE. The research subject is
called as "Production and Control of Pulsed Extremely High Energy Density
State". The chairperson, vice
chairperson, secretary and assistant secretary are Kiyoshi Yatsui (Nagaoka
University of Technology), Shozo Ishii (Tokyo Institute of Technology),
Kazuhiko Horioka (Tokyo Institute of Technology), and Weihua Jiang (Nagaoka
University of Technology), respectively. Regularly, there will be four meetings per year. In 2000, some other technical committees
will be settled.
The main themes to be studied and discussed in the
regular research meetings (Pulsed Power Technology: PPT) are written in the
following: χ development of pulsed power
technology (e.g., power supply, switches, insulation technology), · energy transfer technology of
pulsed power (e.g., electron beam, ion beam, neutral beam, laser beam, pinch
discharge, plasma focus), ¸ production, control,
evaluation/diagnostics, theoretical and computer simulation of extremely high
energy density state, ¹ applications of extremely
high energy density state (e.g., microwave, materials, environment, radiation
source, particle acceleration, flier acceleration, strong electromagnetic wave,
free electron laser, X-ray laser, excimer laser, ultrahigh
pressure/density/temperature/magnetic field strength, inertial confinement
fusion, luminescence/display, diagnostics), and º others.
The regular research meetings (PPT) are open to
participate to everybody who are interested in the pulsed power technology and
associated applications.

The Technical Committee on Electrical Discharge
(TC-ED) has been charged with offering the opportunities for the members of IEE
of Japan in the research field of electrical discharge to present their
achievements, and studying and reporting on current status and future
challenges in electrical discharge engineering. It was established formally in 1980, but its root goes back
to the start of Expert Committee on Electrical Discharge in 1954. In order to meet the objective, a few
subcommittees are organized in the TC-ED every year to survey the up-to-date
subject and their activities continue for three years normally.
In the past, the following subcommittees were
active and published the Technical Research Reports on a relevant subject:
Discharge Simulation Methods, Surface Discharges in Diverged Fields, V-t
Characteristics in SF6, Conduction and Breakdown in Dielectric Liquids, Plasma
Processing, Fundamental Processes in Non-LTE Plasma, Simulation in Non-LTE
Plasma, Field Measurements in Electrical Discharges, Breakdown Mechanism and
Characteristics of Gas Mixtures, Modeling of Long Sparks, Interaction between
Sparks and Laser, Space Charge Effects on Electrical Breakdown in Insulating
Liquids, Effects of Interface and Foreign Matters on Electrical Breakdown in
Insulating Liquids, High Stress Phenomena in Cryogenic Liquids, Plasma
Reactors, Plasma Display, Database on Gas Discharges, Beam and Swarm Data for
Gas Discharges and Plasma; Plasma Chemistry, Electrical Breakdown in Vacuum,
and so on. The total number of the
past subcommittees is 36 and the published technical reports reach 29 at the
end of 1997.
Now eleven subcommittees are running for a
survey of the listed subjects.
Each subcommittee consists of 20-30 members who are the specialists in
the relevant research subject or are interested in it.
The TC-ED is supporting more than ten domestic
research meetings on electrical discharges every year where almost 250 full
papers are reported by professors, scientists and students from universities and
institutes and engineers from industries.
In 1998, "Handbook of Electrical
Discharge" was completely revised after an interval of twenty-five years
through the active support of the TC-ED. This handbook has a special advantage
of including two discs of CD-ROM in which full text of it, database on
electrical discharge and useful simulation software are stored, together with
two volumes of hardcopy of total 1000 pages. The publication project of the
handbook won 1998 Group Writing Award of IEE Japan.
The international and domestic conferences and
annual seminar for young researchers are also promoted by the TC-ED in
cooperation with the Technical Committee on Dielectrics and Electrical Insulation,
IEE of Japan, the Institute of Electrostatics of Japan and the Japan Research
Group on Electrical Discharge which consists of about 400 members whose
backgrounds covers a wide area of electrical properties of solids, liquids and
gases.

This technical committee
(TC) belongs to Power & Energy (P&E) Society of the IEE of Japan. This committee supervises activity of
investigation on technical subjects related to high voltage engineering. Six investigation committees listed in
Table 1 are active in October 1999. The scope of this TC resembles, but is
broader than, that of the CIGRE Study Committee 33 (Power System Insulation
Coordination).
In January 1999, TC on
High Voltage Engineering jointly organized 1st International Workshop on High
Voltage Engineering (IWHV) with TC on Switchgear and Protection, which also
belongs to P&E Society of IEEJ.
The workshop was successfully held at University of Ryukyus in Naha on
the Okinawa Island attended by 97 participants from 7 countries. Selected
papers from this workshop will appear on January 2000 issue of Trans. of IEEJ,
P&E Society, as a Special Issue on IWHV.
Based on this success,
2nd Workshop is planned during Nov. 1-2, 2000 at Tottori City in the week just
before Asian Conference on Electrical Discharge in Kyoto. At this Workshop,
cooperation with other technical committees is extended to include TC on
Electrical Discharge, belonging to Fundamentals and Materials Society. Several
ordinary technical meetings are jointly organized every year with these two
TCs, Switchgear and Electrical Discharge.
TC on High Voltage
Engineering meets four times a year, and a technical visit to the new HVDC
station in Wakayama is planned in the fall of 1999. The members of the
committee other than the chairpersons of the investigation committees are from
universities (4), research institute (1), electric power utilities (4) and
manufacturers (9).

Technical committee on electrical wire
and cables (TC–EWC) is the committee organized in IEEJ Power and Energy
Society, with the committee members from universities, power and communication
utilities, the railway company and cable manufacturers. The committee
supervises the investigation committees dealing with the subjects concerning
electrical wire and cables. In the past, such investigation committees as the
investigation committee on DC cables, the committee on PD (partial discharge)
detection technology and the committee on accessories for power distribution
cables, have been organized. Those investigation committees published such
technical reports entitled as gPD Detection Technologies Applicable to Power
Cable Linesh or gDesign, Construction and Testing of Terminations and Joint for
Power Distribution Cable Linesh.
Two investigation committees are currently running. Their names and
chairpersons are shown in Table 1. In addition to organizing those
investigation committees, the technical committee holds the technical meeting
to promote RD activities for engineers in
this field and provide opportunities of presenting the results of their
technical achievements. Three technical meetings are planned during the fiscal
year in 1999. The TC-EWC usually meets 4 times a year. One of the meetings is
held with a technical visit by the committee members to facilitate
understanding the trends of advanced science and technology. This year the
committee members visited a high-rising residence named Elza-Tower , which is
located in the suburbs of metropolitan area and equipped with the most advanced
facilities.

Electronic
equipment is becoming small in size, light in weight, and high in
performance. The printed wiring
boards for the equipment are designed in fine and high density with multi
layer, which result in small distance and high electric field strength between
the foil conductors on the board.
The insulating failures may occur on the board under such
conditions. Therefore, an
insulating reliability comes up to an important problem for the design of
electronic equipment and systems. However,
the study on the insulating reliability for the printed wiring board has not
been systematically carried out.
One of the
reasons for this may be a low operating voltage in the electronic circuit. Furthermore, it is impossible to
evaluate the reliability of the board by long term testing, because the
electronic products such as personal computer or portable telephone must be
designed within short-range term by request of a market.
In the
previous investigation committee with the insulation reliability of the printed
wiring board, the round robin tests of the ionic migration were carried out by
more than 10 members to establish the evaluation method for the reliability by
the environmental aging test. However,
the tests under various environmental conditions have not been carried out yet.
From these
viewpoints, a new investigation committee has started in April 1999 with 27
members. The main subjects of the committee are as follows.
(1) Survey on test
methods for insulating failures due to the ionic migration.
(2) Survey on the
insulating reliability with multi-constructed printed board.
(3) Survey on insulating
strength between the conductors against surge of high voltage.
We have held
2 committee meetings and one study meeting since the start of this
committee. Now, we are surveying
on practical problems with the insulating reliability occurring in the product
of electronics equipments or products.
At the end of the committee, we will publish the technical report.

The committee was established in April,
1999 with the term of three years. The committee consisted of 30 members from
universities, research institutes, electric power companies, power apparatus
manufactures and user companies of electric power. The diagnosis of insulating
performance in power apparatus is an important research area to estimate the life
limitation of electric apparatus. There are unknown deterioration mechanism
still to be investigated on the insulating material and electric apparatus. The
following activities have been achieved by this committee;
(1)
Investigation
on relation between the deterioration mechanism of insulation material such as
partial discharge, treeing
and other signals for the deterioration.
(2)
Investigation
on the diagnosis for power apparatus and power cable prior to breakdown.
(3)
Investigation
on the prediction of life limitation with rotating machine, Cable, transformer,
capacitor and power system.
The committee has held 3 meetings. In
1999, the committee promote the Asian Conference on Electrical Insulation
Diagnosis, and sent 17 papers from Japan. The committee will be promote the
study meeting with life limitation and diagnosis of Dielectric Insulation
Materials and Electrical Apparatus at Feb. 8, 2000 and Feb 2001.

Dielectrics and Electrical Insulationh, chairperson: late Prof. Ieda) worked
from Jan. 1991 to Dec. 1992. The
committee reviewed the present status of scientific and technical cooperation
in the field of dielectrics and electrical insulation among Japan and Asian
countries and sought the appropriate ways to promote it. As an important activity discussed in
the committee, the gCRC of Electrical Insulation News in Asiah was established
in Apr. 1994 and edited and published "Electrical Insulation News in Asia
(EINA)" No. 1 - 5 (in every September from 1994 to 1998), and will publish
EINA No.6 in November, 1999. The
EINAs have gained favorable responses by questionnaires inserted in distributed
EINAs.

Investigation Committee on Mechanism of Treeing
Degradation
and Influence of Polymer Morphology
N.Shimizu (Nagoya University)
H.Tanaka (The Furukawa
Electric Co., Ltd.)
M.Kanegami (CRIEPI)
Electrical energy is one of the most
important infrastructures. XLPE
cable, widely used in under-ground electric power transmission and
distribution, plays very important role in stable electrical energy supply.
Lifetime of XLPE power cable
is practically decided by treeing degradation, namely electrical and water
treeing. The investigation of
treeing phenomena is of importance concerning with reliability of electric
power system. Much effort has been paid to investigate treeing phenomena, and
fundamental process of initiation and propagation has been gradually
clarified.
However a lot of the detailed
points are still unclear.
Especially the influence of polymer morphology such as spherulite,
amorphous, free volume etc is left unclarified, although it is essential factor
to treeing phenomena.
From this viewpoint, the
committee was established in April 1998 with the term of three years. The main subjects of investigation and
survey of this committee are
1. Initiation
and propagation mechanisms of electrical tree and the influence of polymer
morphology on them.
2. Initiation
and propagation mechanisms of water tree and the influence of polymer
morphology on them.
3. Initiation
and propagation mechanisms of electrical tree originating from water tree and
the influence of polymer morphology on them.
Since the start, we have held 9 regular meetings and 9 secretary meetings. The results of investigation and survey will be published in Technical Report of IEEJ.

Conference on Dielectric Liquids (ICDL f99)
The 13th International Conference on
Dielectric Liquids (ICDL f99) was held on July 20-25, at Nara-ken New Public
Hall in Nara, Japan. It was
sponsored by IEEE DEIS and supported by gThe Commemorative Association for the
Japan World Exposition (1970)h, gKansai Research Foundation for Technology
Promotionh, gNara Prefectureh, and many Japanese Industries. Prof. Katsumi YOSHINO of Osaka University
and Prof. Hisanao YAMASHITA of Keio University organized the ICDL e99.
The ICDL f99 was provided an interdisciplinary forum
for the exchange and discussion of scientific and technological ideas,
knowledge, information, researches and practical experiences on the properties
and applications of dielectric liquids.
It was addressed to physicists, chemists, material scientists and
engineers who are engaged in research and practical application in these
fields.
The Hans Tropper Memorial Lecture at the 13th
ICDL was given by Dr. Werner Fritz Schmidt of Freie University Berlin, Germany,
on the topic of gElectrons, Holes and Ions in Non-Polar Dielectric
Liquidsh.
The 55 oral presentations including 10 invited
lectures, and 131 poster presentations were reported, and 180 persons from 18
countries were attended the Conference as shown in Table 1.
The next ICDL will be held at Technical University of
Graz, Austria, chaired by Prof. Juergen GERHOLD in 2002.

The 3rd Korea-Japan Joint Symposium on Electrical
Discharge and High Voltage Engineering (1998 K-J Symposium on ED & HVE)
The 3rd Korea-Japan Joint Symposium on Electrical
Discharge and High Voltage Engineering was held on Oct. 19-20, 1998, in Main
Administration Bldg. of Pusan National University, Pusan, Korea. It was
organized by Electrical Discharge and High Voltage Society of KIEE, Korea, and
co-organized by the Technical Committee on Electrical Discharge of IEEJ, Japan.
The chairman of the conference was served by Profs. Kwang-Sik Lee and Chung-Hoo
Park. The symposium has been planned to provide the opportunities for
scientists and engineers to.
All of the fifty submitted abstracts were reviewed,
and forty three papers are accepted and published in The Proceedings of 1998
Korea-Japan Joint Symposium on Electrical Discharge and High Voltage
Engineering, along with the two invited papers.
First presentations were two primary talks entitled
gDischarge in Space Environmenth by Dr. Meng Cho, Japan, and gA Comparison of
Various After Laying Test Methods applicable to 22.9kV CN/CV Distribution Power
Cablesh by Prof. J.K. Koo, Korea. Sixteen papers were assigned to the oral
sessions and twenty seven papers to the poster session, both sessions covered
the topics of High Voltage Testing and Measurement Techniques, Partial
Discharges and Diagnostic Techniques, Electrical Breakdown in Vacuum, Gases,
Liquids and Solids, Electrical Discharge and their Applications, Electric Field
and Their Applications, Electrical Insulation and Lightning.
A number of active discussion and information exchange
were conducted during the session as well as coffee break and post-session
time. In particular many younger researcher and engineers including master and
doctor course students presented their papers and faced to Q & A in
English. We believe that this sort
of experience by younger students will contribute to their life in future.
Seventy nine participants from
four countries: 45 from Korea, 18 from Japan, 3 from China, and 1 from
Pakistan, attended the symposium, conference dinner, and post conference tour.
The next symposium will be held
in Kita-Kyushu, Japan on Oct. 25-26.
