Abstract: The paper makes comparative analysis of the requirements of circuit breakers tolerant transient recovery voltage (TRV) in IEC standard and IEEE standard. The authors based on the IEC 62271 special requirements of circuit breakers tolerant TRV in special circuits,collect parameters of auxiliary transformers, common enclosure buses and other equipments in a nuclear power plant, and apply the calculation method from IEC standard to get the theoretical values (expected values) of tolerant TRV and transient recovery voltage rising rate (RRRV).It is verified by T60 type test of circuit breakers that the VD4 circuit breaker meets the requirements of tolerant TRV.
Key words: IEC standard; nuclear power plant; middle-voltage circuit breaker; transient recovery voltage; T60 type test
