Design and Implementation of Efficient Algorithm for Quality Assurance of Smart Energy Meters During Mass Production

To ensure the quality of the process of energy meter manufacturing, the parameters which are electrically connected are manually calculated after every single step. The process of measuring manually become outdated, erroneous, and it also take more time rather than the automatic, effort and human resources. In addition, it can be easily manipulated and can go ahead to lower products being moved, either because of deliberation or because of evil intents. With incorrect readings of the electrical parameters, the reliability of product to work has been reduced. To improve the reliability of the calculation of electrical parameters and make the process quicker, automated measurement system with application software was developed. When the energy meter is attached to the test bench, the software measures all the parameters and transmits to a data base system i.e. Meter No., Password, kWh, kVarh, Maximum Demand (MD) Interval, Cumulative MD of Tariff 1 & Tariff 2 and MD Counts etc. These parameters will be checked at every step to manufacturing and while moving from one lab to another lab and finally will be compared with previous parameters record to check any abnormal behavior of the product.
