Product Description

Electric energy meter is an instrument used to measure electric energy, also known as watt hour meter, fire meter, kilowatt hour meter, which refers to the instrument used to measure various electrical quantities.
When using an electric energy meter, it should be noted that the meter can be directly connected to the circuit for measurement under low voltage (no more than **0 V) and low current (tens of amperes). In the case of high voltage or large current, the electric energy meter can not be directly connected to the line, and it needs to be used with voltage transformer or current transformer.
