| Abstract: | The simulation model is built with ATP-EMTP for the closing without load of transformer and the closing process of a 750 kV transformer is simulated.Its overvoltage waveforms are compared with those of a 750kV transformer startup test.The overvoltage factors during the primary-side closing of transformer without load are studied by simulations with different closing conditions and results show that,the overvoltage waveforms are composed of two parts:one is the steady voltage,coupled from low-voltage winding... |
| Keywords: | 750kV electric transformers closing without load overvoltage resonance EMTP computer simulation |
