The energy meter is used all around the world for measuring the usage/ consumption of power. This requirement is not only for households but also for industrial areas where electric power is consumed. Electric meters sense the amount of current in amps and as per the standards of 240V/ 400V depending on the national standards calculates the power consumption which is simply current multiplied by the voltage. This value obtained is in watts, and can be converted to Watt hours a unit of power consumption with respect to time and displayed on a screen(digital or analog).
The parts that are used for current sensing such as flux concentrators/ shields etc. The meter measures current with an assembly inclusive of hall sensors/ shunt/ both. PML provides the required parts for current sensing which includes laminated flux concentrators, shields, shunt etc.
