“…Due to privatization and globalization now there is additional pressure to reduce the prices of the meters and testing panel and provide enhanced functionality. This paper presents a new approach to develop portable test module by which Electricity Utility Officer [2] can verify accuracy of the energy meter before installation and in field (customers residence) and satisfy all queries raised by customer. Power consumed by load = power indicated by instruments -power loss in voltmeter.…”

Energy Meters installed in the consumers premises need to be tested since if more units are calculated with less amount of power consumed, the user in loss. At the same time, if fewer units are calculated with more amount of power consumed, the electricity boards are at loss. This results in an increasing demand on the means to test the energy meters correctly with adequate frequency and ease to ensure the correctness of the measurement of the meter. Field-testing of meters will therefore increasingly become necessary. Up till now, meters were tested and calibrated by injecting power from a fairly stabilized stationary source into the device under test with a reference meter connected in the circuit. The accuracy of the test was determined by the accuracy of reference meter, which is referable to the national standard, and not by the power source.
