Product Description
It composes of high-stability single-phase program-controlled power source and single-phase standard watt-hour meter. It applies to the calibration of electronic and electro-mechanical single-phase active and reactive watt-hour meters as well as multi-function watt- hour meters and can provide us with rich electric quantity information such as AC voltage. AC current, phase difference between voltage and current, power factor, active power, reactive power, apparent power, frequency and so on. It can be used in such area as product research and development, product maintenance, and product test at production lines. By using the underlying dynamic link library users may develop their own automatic meter calibration software.
