Three-phase multi-functional watt-hour meter is designed to meet the needs of power monitoring in power system, industrial and mining enterprises, public facilities and intelligent buildings. It can measure all common power parameters, such as three-phase current, voltage, active and reactive power, electric power, harmonics, etc.
It has a high performance-price ratio and can directly replace conventional power transmitters and measuring instruments.
Because the power meter also has perfect communication network function, so we call it network power meter. It is very suitable for real-time power monitoring system.
