RT***3B Portable Three Phase Energy Meter Test Instrument
Overview:
The RT***3 Series Portable Three Phase Energy Meter Test Instrument
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.
