%X 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.
