Introduction to Energy Meter
An electric energy meter is a meter used to measure electrical energy, also known as an watt-hour meter, a live meter, and a kilowatt-hour meter. It refers to a meter that measures various electrical quantities. In order to meet the needs of different occasions and markets, various electric energy meters have been born.
According to the purpose, it can be divided into: active power meter, reactive power meter, maximum demand power meter, multi-tariff power meter, prepaid power meter (magnetic card type, IC card type, code type), multi-function power meter and Smart energy meters, etc.
According to the working principle, it can be classified into: induction type (mechanical type), static type (electronic type), electromechanical type (hybrid type).
According to the nature of the power supply, it can be divided into: DC and AC type.
According to the structure, it can be divided into: integral type and split type.
According to the phase line can be divided into: single-phase, three-phase three-wire, three-phase four-wire electric energy meter.
According to the wiring method, it can be divided into: direct access type and indirect access type.
When each electric energy meter leaves the factory, it should have its own model and nameplate to explain its functions, main technical indicators and conditions of use, etc., to facilitate the use of users.
