| Abstract: | Have power cut dispatching through system analysis of line inspection. Test the error of instrument transformers in service at power exchange point in great electric power grid widespread. Batch calculates the composite error using EXCEL. Analyze and evaluate the integral status about metering accuracy of transformers. The economical affection caused by composite error of transformer is considered and improving method is discussed. Therefore, wrongful dealing at the power exchange point in electric power gr... |
