Abstract :
This on-line PD monitoring system can monitor partial discharge in two three-phase transformers continuously. It has the functions with fault reminiscence, fault warning and fault location. By means of using wide-band, multi-channel, high sampling rate and large capacity data acquisition system makes system has a good basis, it can use various kinds of digital signal processing method. Furthermore various kinds of data processing method can be added into the system flexibly by taking the Component Object Model as the basis of the whole software. This system has good expansibility and flexibility and can fit the requisition for different equipment and monitoring parameters
