Identification of Power Leakage and Protection of Over Voltage in Residential Buildings

In many residential buildings the electrical wires of individual houses are laid in same conduit pipe and some mistakes could be made identifying similar coloured when they pipe. Most faults caused by neutral interconnection wiring system. Usually connected to bus within panel board or switchboard, "bonded" earth ground. our secondary distribution, tree system supply is mostly utilized. The voltage each phase will maintained at rated value even during unbalanced load conditions. If wire connection poor different from one another, such an isolated point called floating always changing. This reason for over causing damage appliance’s which should protected. this paper, a smart that identifies power leakage provides protection building proposed.
