Abstract


This paper presents the current state of the overvoltage protection of generator transformers in power plants of the Power Company of Serbia (EPS) and gives a critical overview of their overvoltage protection. Recommendations for the purpose of its control are provided. Improved overvoltage protection of power transformers in the EPS is suggested. A critical review of the state of earthing points of the generator transformers is also given.
