Energy meter for AC is an instrument used to measure AC energy, usually composed of current and voltage sampling, signal processing, calculation, and display. It can measure parameters such as real time power, cumulative energy, and maximum load of AC electricity, and is widely used in the fields of power, energy, and industry.
Energy meter for AC can be divided into single phase energy meters, three phase three wire energy meters, and three phase four wire energy meters according to the circuits they use. According to their uses, they can be classified as active energy meters, reactive energy meters, complex tariff energy meters, prepaid energy meters, anti tamper energy meters, etc. In addition, there are new types of energy meters such as electronic energy meters and smart energy meters.
When using Energy meter for AC, they need to be correctly connected to the circuit to work properly. If connected incorrectly, there may be errors in energy counting or even damage to the energy meter. When wiring the meters, besides following general rules, it is necessary to verify and refer to the wiring instructions provided with the energy meter. During installation, the power supply to the input terminals must be disconnected to ensure the safety of the installation operation.
