Discussion on the Interaction between Transformers and the Power Systems

Guilherme Sarcinelli Luz ; Cigré-Brazil Joint Working Group JWG – A2/C4-03 – Electrical Transient Interaction between Transformers and Power Systems Brazil

Sažetak

A general increase in transformer dielectric failures in the Brazilian transmission system, some of
them with no specific causes, motivated the start up of a Cigré Joint Working Group JWG A2/C4–03
Electrical Transient Interaction between Transformers and the Power System. This group has been
gathered to assess and discuss the different types of electrical transient interaction between
transformers and other components of the T&D power system that could explain some of these
failures.
The main focus of the JWG is to pursue an improvement of the system reliability based on
recommendations regarding the electrical transient interaction between transformers and the power
system. This takes into account the necessity of detailed transient studies looking for an upgrade in
equipment specifications, system planning and operation criteria. The working group started its
activities in May 2005 and is composed of around 30 members, representing utilities, research center,
manufacturers, universities and the national grid system operator.
The objective of this paper is to present the work that has been carried out so far by the JWG including
the main discussions and the conclusions already reached.
