The found and dealt with the defaults of non-synchronous closing in phase-to-phase for 5033 circuit breaker at 500 kV Fanchang station

This text described the East China Power Grid Company and its subordinate companies through carried out the com- missioning of 500 kV transmission system project,found Fanchang 500 kV substation 5033 circuit breaker has non-synchronous closing in phase-to-phase defaults.Technical staff analyzed the recorded waveform with the equipment structural characteristics of wave to determine the reasons for the defaults.The related units eliminates wholeheartedly with the above defaults.
