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

The three-phase watt-hour meter fully meets the relevant technical requirements of the Ministry of Standards DL/T645-1997 and the national standard GB/T17215-1998 for 1 or 2 single-phase; it has the characteristics of good reliability, small size, and 35mmDIN standard installation; and It has good anti-electromagnetic interference, low self-consumption and power saving, high precision, high overload, high stability, anti-theft and 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 systems and three-phase four-wire systems.

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