There are several models of three-phase
meters_ Introduction of specifications and
models of three phase ammeter
The electric energy meter is a special instrument for measuring electric energy and the most basic equipment for electric energy measurement, referred to as an electric meter.
The following introduces the classification, model and the meaning of the signs and symbols of the electric energy meter.
1) According to the circuit used, it can be divided into DC electric energy meter and AC electric energy meter. AC power meters are commonly used. AC electric energy meters can be divided into single-phase electric energy meters, three-phase three-wire electric energy meters and three-phase four-wire electric energy meters according to their circuit and phase line.
2) According to the working principle, it can be divided into electrical and mechanical watt-hour meters and electronic watt-hour meters.
3) According to the purpose, it can be divided into active electric energy meter, reactive electric energy meter, maximum demand meter, standard electric energy meter, multiple rate time-sharing electric energy meter, prepaid electric energy meter, and multifunctional electric energy meter. The active energy meter is commonly used.
4) According to the accuracy level, it can be divided into ordinary installation electric energy meter (0.2, 0.5, 1.0, 2.0, 3.0 grade) and portable precision electric energy meter (0.01, 0.02, 0.05, 0.1, 0.2 grade). Commonly used is the 2.0 level meter.
