A    three phase electricity meter    is an electric energy meter used to measure the electric energy output (or load consumption) in a three-phase AC circuit. Its working principle is exactly the same as that of a single-phase watt-hour meter, except that the structure adopts multiple sets of driving components and multiple aluminum plates fixed on the rotating shaft to achieve the measurement of three-phase energy

The three phase electricity meterfully complies with the relevant technical requirements of 1 or 2 single-phase in the national standard DL / T645-1997 and the national standard GB / T17215-1998; it has the characteristics of good reliability, small size, and 35mm DIN standard installation; and has Good anti-electromagnetic interference, low self-consumption power saving, high precision, high overload, high stability, anti-stealing electricity, long life.

According to the nature of the measured electrical energy, three-phase watt-hour meters can be divided into active watt-hour meters and reactive watt-hour meters; due to the different wiring forms of three-phase circuits, there are three-phase three-wire system and three-phase four-wire system.

The   three phase electricity meter  is suitable for measuring three-phase four-wire AC active energy with a rated frequency of 50Hz or 60Hz. For fixed installation indoor use, suitable for the environment, and the air does not contain corrosive gases and avoid the effects of dust, mold, salt spray, condensation, insects, etc.
