DESIGN AND DEVELOPMENT OF ELECTRONIC ENERGY METER

Abstract

In past, traditional electro mechanical meters have been the instrument used by the utility companies to measure residential and commercial power consumption. In recent years electronic energy meter has gained an increasingly important role in energy measurement and popularity due to various advantages over the traditional electro mechanical meters like higher energy measurement accuracy, provision for networking and low cost etc. This thesis entitled “Design and Development of Electronic Energy Meter” deals with design of different blocks of single phase and three phase electronic energy meter such as design of current sensor, designing of voltage sensor, designing of power supply, designing of display unit etc. Tests were performed on single phase and three phase electronic energy meter to prove the conformity of the requirements. The basic instrumentation circuit of single phase and three-phase electronic energy meter has been identified and implemented using discrete components. ...
