RT3303 Portable Three Phase Energy Meter Test Bench

Overview:
The RT3303 Series Portable Three Phase Energy Meter Test Bench comprises of high-stability three phase program-controlled power source and three phase standard watt-hour meter.
It applies to the calibration of electronic and electro-mechanical single phase and three phase active and reactive and reactive watt-hour meters as well as multi-function watt-hour meters.
It 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 hung with 1 to 3 meter stations. It is embedded with error processor or can be inserted with error processor.
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 developed by Rowwin Test, users may develop their own automatic meter calibration software.
