Active and reactive energy meter, which is a device that can measure both active and reactive energy in a circuit. Nowadays, electronic multi-function energy meter can accurately measure active, reactive power and energy.It reflects the ability of an AC power source to do work on a resistive element, or the amount of electrical energy converted into other forms of energy in a unit time. In fact, it is the average instantaneous power over one cycle, so it is also known as the average power.
Reactive energy meter, the inductance or capacitance element and the alternating current source reciprocate exchange of power called reactive power. Short for "reactive", with the symbol "Q". The unit is Var or kilovar (KVar). In an AC circuit, any component that has an inductive or capacitive property will establish a magnetic field around an inductor coil or an electric field between the plates of a capacitor.
With the development of communication technology, Internet of Things technology and electronic technology, more and more functions are added to active and reactive energy meter. The ratio of active power and reactive power reflects the efficiency of electricity consumption. When the reactive power is too large, the equipment needs to be optimized, such as reactive compensation to reduce the reactive power and ensure the quality and efficiency of the power grid.

It is necessary to use active and reactive energy meter in power systems for electricity monitoring, which helps to ensure the stable operation of the power system, improve power quality, optimize the distribution of power resources to meet the needs of the operation of the power market, and better manage and maintain the power system.
