A Study on the 22.9KVY Multiground Distribution System

This paper is a part from the series study on the 22.9KVY multiground destribution system and its is divided into three parts as follow. A.C. Network Analyzer study on the load current flow when one phase line of the feeder is out of seroice because of cutting. A.C. Network Analyzer study on the increasing zero sequence current in the good feeders when one feeder is under fault of single phase short. Field test report of the common use of open telephone line on same poles of 22.9KVY distribution system.
