Abstract

The insulated state is one of the most important problems of large power transformer safely running in power system. The most efficient method in monitoring the running transformer’s insulated state is to extract partial discharge (PD) signals in real-time. In this paper, a hardware system of partial discharge online monitoring for large power transformers is presented. In hardware circuit implementation, notice to choose signal sensors, A/D convert unit and filter circuit are reasonably designed, at the same time, large capability storage circuit and the fault diagnosis system are designed.
