Three Phase Watt-hour Meter

Three phase watt-hour meter is also known as multi phase watt-hour meter. The difference between three phase watt-hour meter and single-phase meter lies in the different amounts of the measuring elements. The three phase watt-hour meter has three 220V measuring elements, and is applied to three phase power supply systems. The standard three phase power supply system falls into two types: Three Phase Four wire (three live wires, one ground wire) and Three Phase Three Wire (three live wires). Three phase meter indicates the phase difference and is used for accurate and fast reading of active energy consumption from a three-phase AC electricity net. Mainly applied to three phase power supply systems, this three phase watt-hour meter is generally applied to industries where there is great power consumption.
