Overview
Emissions And Stack Portable Electricity Hour Meter Calibration Device is suitable for metering and testing centers of power grid companies, power management departments of power supply companies, national energy metering and testing institutions at all levels, as well as industrial and mining enterprises and electricity meter manufacturers for quick and small batch testing of all kinds of single and three-phase electricity meters. It can also be used as a high-standard power source. The device adopts a high-precision power frequency AC collector composed of two digital signal processors (two DPS for signal processing and one for power acquisition and calculation) and a 16-bit high-speed digital-to-analog converter, and then combines the ARM processor and the operating system as the operation control platform. The new generation of portable three-phase electricity meter calibration device is developed.
