Principle Of Single Phase Meter, Three Phase Meter And Various Meters
Electric energy meter is an instrument used to measure electric energy, also known as watt - hour meter, fire meter and kilowatt-hour meter. It refers to an instrument used to measure various electrical quantities. Electric energy meter (can be divided into coin – operated meter, magnetic card – operated meter, and electric card – operated meter), loss electric energy meter, multi-function electric energy meter, and intelligent electric energy meter. According to the working principle: it can be divided into inductive (mechanical) meter, static (electronic) meter and electromechanical integrated (hybrid) meter. According to the nature of the connected power supply: it can be divided into AC meter and DC meter. According to structure: it can be divided into integral meter and split meter. According to access phase line: it can be divided into single phase meter , three phase meter and three-phase four-wire electric energy meter. According to the accura...
