Voltage Measurement System Comparison and Uncertainty Evaluation for UHV Field Special Test
Authorized by State Grid Communication & Construction Company,we have undertaken 1 000 kV transformer field commissioning long-induced voltage-endurance test with partial discharge in Shanghai Huxi UHV Substation.Due to the different voltage measurement method used in this test,which is closely related with the test results,this research makes comparison and uncertainty evaluation on the voltage measurement system.
