Research on calibration method of fault flashover test instrument for power cable using low voltage pulse method

The fault flashover test instrument for power cable is an indispensable equipment in cable fault detection work. Low voltage pulse method is one of the common methods for cable fault testing. Accurate and reliable measurement values are of great significance for fault flashover test instrument for power cable using low voltage pulse method. This paper presents a calibration method that is easy to operate, mainly uses common equipment as measurement standards, and has a low calibration cost. The article elaborates in detail on the key steps in the calibration process, including the selection of standard equipment, operation methods, data processing, etc., and verifies the effectiveness of the proposed calibration method through experiments.
