An Energy meter includes current and voltage input, a surge protection section, a measurement device. The measurement device will generate power consumption measurements based on current input and voltage input. The surge protection section includes components like resistor, inductor, capacitor, Metal oxide varistors, and fuse. Metal oxide varistors are important devices which will mitigate the voltage spikes caused from lighting and other external sources. Every electronic equipment will undergo failure due to this overvoltage and spikes hence it is important to choose the proper overvoltage protector for the electronic equipment. This paper presents the performance analysis of the metal oxide varistors under different load conditions in an electronic Energy meter and a solution based on regression analysis for prevention of the failure of installed commercial energy meters hence resulting in reduced maintenance costs to the utility company.
