DESIGN AND DEVELOPMENT OF SINGLE PHASE STATIC ELECTRONIC ENERGY METER WITH COMMUNICATION CAPABILITY

Abstract

The accurate measurement of electricity supply and subsequent billing to residential properties has traditionally been achieved through electromechanical meters. Although widely used this solution has several disadvantages including long term accuracy, cost of calibration and limited communication. These issues can be overcome using digital power meters where it is possible to achieve long term accuracy by removing analog components which are prone to drift over temperature and time. The goal of this project is to design an electronic energy meter which calculates instantaneous power at all power factor and gives low frequency pulse output which is directly proportional to real power .This low frequency pulse output is further used by a microcontroller which calculates energy in terms of Kwh and displays it on LCD. The function of microcontroller is not only limited to display of Energy but it also calculates maximum demand, detects different types of tamper such as magnet...
