Summary report of the Technical Sessions for colloquium on SC A2 on Transformers

A special theme address for Study Committee A2 was delivered by Ms. Seema Gupta, the Observer Member for India in Study Committee A2. She explains the main challenges facing transformer engineers in India.

• Preferential Subject 1 for Study Committee A2 was “Advances in Transformer Design, including use of new materials”. The session co-chairs were Mr. Jan Hayek and Mr. Virenda Lakhiani. The keynote address was given by Mr Martin Stoessl, who emphasised some of the points made previously in the special opening address. A total of 13 papers were presented for this Preferential Subject. Subjects for the papers included applications and design concepts (3); improvements in transformer design (4); improvements in modelling (3); use of new materials (2); and risk assessment methodologies (1). The session co-chairs selected the following as the best paper in this Preferential Subject: Patrice Hurlet “Improvement of transformer specification to enhance reliability of key power transformers (GSU for nuclear power plants)”.
  The following paper was also highly commended by the Study Committee Chairman: “Pramod Rao et al, “Transformer bushings: current technology trends, development and its relevance in monitoring bushings in service”.
• Preferential Subject 2 for Study Committee A2 was “Quality Assurance and Short-Circuit Withstand Capability of Transformers”. The session co-chairs were Mr. Henk Fonk and Mr. RK Tiwari. The keynote address was given by Mr P. Ramachandran, who used his experience to explain developments in the short-circuit withstand capability of transformers from 1885 to the present day. He suggested that short-circuit type test reports for power transformers should be valid for 10 years. He also suggested that transformer operators should consider ordering a short-circuit test for series of more than 10 transformers. A total of 8 papers were presented in this Preferential Subject. Subjects for the papers included improvements in transformer construction (2), improvements in transformer safety (1), and short-circuit withstand capability (5). The session co-chairs selected the following as the best paper in this Preferential Subject: Professor Vasily Larin et al, "Russian practice on tests and confirmation of power transformers ability to withstand short-circuits”.
• Preferential Subject 3 for Study Committee A2 was “Operational Experience in the Field of Transformers”. The session co-chairs were Dr Patrick Picher and Dr Aradhana Ray. The keynote address was given by Dr BN De Bhowmick, who gave more details on the main challenges facing transformer engineers in India and recent steps taken to meet them. A total of 10 papers were presented in this Preferential Subject. Most of the papers were on the subject of transformer field testing (7). The session co-chairs selected the following as the best paper in this Preferential Subject: “Professor Stefan Tenbohlen et al, “UHF sensor placement on power transformers for PD monitoring”

Closing remarks were made by Ms. Seema Gupta, the Observer Member for India in Study Committee A2, and by Mr. P.P. Wahi, Director of CBIP and CIGRE India. Special thanks were given to Mr. Vishan Dutt of CBIP, for his role in organising the Joint Colloquium.
