What is a three-phase energy meter and what it is used for
A three-phase energy meter is a device designed to measure and record electricity consumption in a three-phase system. A three-phase system is a type of electrical system that supplies electricity through three phases and a neutral. This type of system is commonly used in industrial, commercial, and other applications where more electricity is required than a single-phase system. The current feed-in must be carried out through an amperometric transformer, and the secondaries can be grounded.
Device usage
The device features on the front:
- a green LED to indicate the presence of power
- a red LED that identifies the energy count (1 blink = 1/4 kWh)
- a yellow LED that identifies a connection error
- a transformation ratio selector switch (TAs are chosen by dip-switch selection under the front door)
- a 7-digit non-resettable electromechanical numerator
- MID instrument metrology seal
