W ELCOME TO ARWtr 2004
On behalf of the Organising Committee, may w e give you the warmest welcome to ARWtr
2004 and to Vigo.
This meeting is devoted entirely to transformers. ARWtr 2004 appears in it first edition,
shaped as unique event in the world covering the three main areas related to
transformers: High Frequency Transformers; Power Transformers; and Instrument
Transformers.
An international group of outstanding transformer experts , the key speakers, will present
and stimulate discussion on contemporary economic, design, diagnostics and
maintenance aspects of modern transformers.
We would like to thank all participants and committee members who have made
important contributions. Especially to section chairmen, for their invaluable effort by
reviewing the proposals and organising of the programme.
In addition to the technical sessions, a number of social events have been arranged. On
Thursday evening we will have a Reception at Pazo de Catrelos (Castrelos´s Galician
Place) and Friday evening the Dinner at Restaurante el Castillo (Castle’s Restaurant).
After workshop days, on Sunday 31, an optional Santiago de Compostela trip is
organised for all participants who whish.
We hope you find the Workshop enriched technically and scientifically, and stimulating for
making many fruitful personal contacts for future collaborations. Also, we whish that you
enjoy your visit to the Vigo area and Galicia autonomous country.

ARWtr 2004
AIM AND TOPICS
The aim of the Advanced Research Workshop on Modern Transformers (ARWtr 2004)
is to provide a meeting of specialists among industrial and academic world and
promote an intense exchange of knowledge about new trends and issues on modern
transformers, into the three main areas: High frequency; Power; Instrument.
The main topics are concerned with: Design & test; Diagnostic; Maintenance; Materials;
Economics; and New technology.
In particular are involved the following aspects: Acceptance test; Computation and
problems of windings; Computation and problems of cores; Computational software;
Criteria for the short-circuit proof design; Design and modelling; Heating and cooling;
Life management of transformers; Mechanical design of tanks, undercarriage; Noise
and vibration; Optimal selections between different core types; Stray losses, screening
and local excessive heating hazard; Superconducting; Economic in transformer
management.
PUBLICATION
All papers presented at the ARWtr 2004 will be collected in the Workshop Proceeding.
After the event, the lectures and some of the papers accepted in the reviewing process,

W EATHER
Usually in October, the temperature is between 23 ºC during the day and 10 ºC in the
night. Intervals sunny and cloudy days with some showers.
TO GET VIGO
Vigo is well connected to the world by means of a good network of motorways, its airport
(Peinador) and its railway station.
By train (http://www.renfe.es/): the train station is located in the city centre just near
Hotel IBB Ensenada. There are daily express and "Talgo" trains to Madrid and Barcelona.
By plane (http://www.aena.es ): Peinador airport is 10 kilometres from the city centre. The
price of the taxi from Peinador to city centre is around 20 Euros. It has a wide range of
scheduled flights to Madrid, Barcelona, Bilbao, Valladolid, Paris and Frankfurt, as well as
charter flights. Santiago de Compostela (Labacolla airport: 90 km far by motorway) and
Porto-Portugal (Sa Carneiro airpot: 100 km far by motorway) are useful international
Connections. These last two airports are linked by buses.

SOCIAL PROGRAMME
On Thursday evening 28 October a Reception will be held at Pazo de Castrelos at about 8.00
PM. Pazos (Palaces) are stately mansions built in the country either as permanent or temporary
residences for Galician noblemen and illustrious families. They were mainly built during the 17th
and 18th centuries and their dimensions, together with the coats of arms they display, towers,
sun lounges, chapels and the lush gardens which surround them, make them outstanding.
On Friday 29 October, the Dinner will be held at Restaurante el Castillo at about 8.00 PM.
Restaurante el Castillo has an exceptional view over the most beautiful of the Rias (natural
estuaries formed by mountains, beaches and sea) which is named Ria de Vigo. The Dinner
Menu will be the well world known fresh shellfish and fish of Vigo, directly form the Ria.
POST-EVENT T RIP
On Sunday 31 October, a post-event trip will offer to participants and accompanying people. It
represents a unique opportunity to visit the exquisite scenery of Santiago de Compostela.
Santiago an UNESCO-World Heritage City is a precious jewel in stone. From the 9th century
onward, European Christendom was to fix its gaze on Compostela. There, an ancient tomb is
recognized as that of the Apostle St. James the Greater. The Romanesque Cathedral of
Santiago, begun in 1075, is the acme of the temples of pilgrims. Nowadays, it is the
administrative capital of Galicia. This year, Santiago celebrates its first (Holy Year) Xacobeo
2004 of the new millennium in honour of Saint James.

SECTIONS
The main subject of the ARWtr 2004 is Transformers, which is divided in three important
areas or Sections:
- High Frequency Transformers (HFT)
- Power Transformers (PT)
- Instrument Transformers (IT)
Each SECTION is coordinated by a Chairman:
- High Frequency: Prof. Ertan
- Power Transformer: Dr. Kazmierski
- Instrument Transformer: Prof. Lesniewska
SESSIONS
The Section consist of Sessions, which are collected into three kind of sessions as
following:
Oral Sessions (45 minutes)
For lectures of key speakers. Each lecture is a oral session itself conducted by one/two
session chairman/en. In the oral session the key speakers will deliver fixed lectures on
9
ARWtr 2004
key topics of transformers during 45 minutes period (25-30 for presentation and 20-15 for
discussion).
Poster Sessions (60 minutes)
All participants will have the possibility of presenting their own works and contributions
during the coffee break-poster sessions. Each poster session (60 minutes) covers the two
coffee breaks (30 minutes) per day: one mid-morning and another one mid-afternoon. In
each poster session there will be two chairmen.
Special Sessions (45 minutes)
The special session is devoted for discussion of the current challengers/conclusions and
recommendation for future research and actions. Like a “Table”, will be conducted by a
session chairman and supported by 2-3 specialists. They will set the different points and
lines of discussion during 20-25 minutes and state open discussion during the last 20
minutes.
