Abstract

Electricity meters are used in measuring the quantities of electrical energy consumed by a load. They are used by distribution companies to measure the energy consumed by a customer which in turn is used in billing them. Currently, there are only two types of energy meters. The Electromechanical Energy Meters and the Electronics meters. In the Electromechanical type of meters, the electrical energy consumption is measured based on the induction principle recorded by the resolution of the counter. The main principle used here is Electromagnetic Induction. While in the Electronics Meters, also known as Solid State meters, no moving part is seen, no mechanical parts are present. All we see is the Microcontroller, Analog Front End (AFE), Resistors, Diodes all mounted on the Printed Circuit Board. This paper presents the importance of an effective calibration on Electronics meters. A calibration test was carried out on 15 Solid State meters on the Test Bench using the Telemetry Test Equipment (TMTE) software. Then a comparison was made between the data obtained from the passed calibration meters and the failed calibration meters in terms of their error. From the result gotten, it was seen that 7 meters passed calibration and the remaining 8 failed. These failed meters need to be worked upon and they recalibrated before they are certified to be used for a residential, industrial or commercial purpose otherwise, there will be a fluctuation and inconsistent measurement of basic electrical quantities.
