Method for judging and processing single-phase earth faults by using electronic mutual inductor

The present invention relates to a method for determination of single-phase ground fault processing based on the electronic transformer, comprising the following steps: Step 1: single-phase ground substation feature quantity detecting single-phase earth feature amount acquisition means and line detecting means and the amount of single-phase ground feature group package uploaded to the fault location in the master system processor; step 2: fault location processor within the master system single-phase ground fault location. The present invention is characterized by a single-phase ground substation amount detecting means is mounted in the substation and the installation of the line of the collection amount detection means single-phase ground line feature quantity wherein single-phase ground, then the fault location in the master processor system can quickly, single-phase to accurately determine the position of the specific region segment, a distal end remote control switch can also be isolated from the recovery process, increases the accuracy of the determination of single phase ground single-phase ground, to ensure the safety and reliability of work distribution network , effective protection of the network equipment and electrical equipment.
