The function of neutral wire in 3 phase 4 wire system is to serve as a return wire for general domestic supply system. It consists of three phase wires and a neutral. Where supply is to be given to a large establishment like hotels, offices, hospitals the system of three phase four wire supply is adopted. The supply to houses, small offices, shops other premises requiring small loads is taken from the distribution mains at 230 volts with the help of one phase and one neutral wire. The voltage between any phase wire and neutral is 230 volts and between any two phase wire is 400 volts. The distribution is generally single phase two wire and three phase four wire. The connections of the windings of the transformers installed in the sub-station are in delta on the primary side and in star on the secondary side. 400 volts for bulk consumers and 230 volts for general domestic consumers. The voltage is ultimately stepped down to 400/230 volts i.e. The power is then distributed to various sub-stations located at various places and localities. The power from generating stations is transmitted over long distances through transmission lines to various receiving stations. After reading this article you will be able to understand some very amazing facts about need of neutral wire in three phase four wire distribution system. In this article I am discussing the function of neutral wire 3 in phase 4 wire system.
