The UHV primary equipment that is newly installed and has been operated for a period of time after maintenance must be subjected to on-site high-voltage tests before it is put into operation. By analyzing and calculating the key technical indicators of the field test device, the application of high-resistance field partial discharge and withstａnd voltage test research can help the accuracy of on-site diagnosis of UHV AC and DC equipment, reduce the test time, and improve the performance of UHV equipment usage efficiency.
