Three-phase circuit active energy meters are used in three-phase three-wire circuits and three-phase four-wire circuits. According to different load requirements, they can be
measured by one meter method, two meter method, or three meter method. Each electric energy meter is composed of a voltage coil and a current coil. The voltage coil and current coil of the first group of components
are connected to U respectively. , and ammeter; the voltage coil and current coil of the second group of components are connected to Uwy and the second ammeter respectively. When wiring
, if
any terminal is connected incorrectly, the aluminum plate will rotate reversely, or even though it rotates forward, the reading will not be equal to the power consumed by the three-phase circuit
. This should be paid special
attention to.
