| Abstract: | On the basis of analyzing the leakage fault laws of distribution network, a new intelligent comprehensive protective system suitable for the network with various neutral-point wiring modes is designed. The principles of protective system are emphatically analyzed and the hardware structure and software block diagrams are introduced. The trial running shows that the protective system is stable in performance and reliable in operation and will be of great popularization values. |
