PC Based System for Partial Discharge Detection and Analysis

Partial discharge (PD) measurement is a non-destructive insulation test of HV equipment. It is a vital test for several HV apparatuses according to IEC standards. The PC based system is applicable for PD measurement of equipment such as HV capacitors, transformers, insulators, cables, and electrical machines. In this system, PD pulses generated in the test-object are transmitted to the PC based PD meter, which consists of a high-speed A/D card, a software environment for PD signal processing, an external calibrator and an external synchronizing system. This system has several features to achieve superior performance.
