INTRODUCTION:
The Portable Three Phase kWh Meter test equipment is used for grid corporation of measurement
and energy testcenter, management department of power supply bureau, national energy
measurementof testing authorities, andalso used to test each kind of single/three phase
kWh meter of industries and mining enterprises as well as electricmeter manufacturers.
Meanwhile, the calibrator also can be used as one high precision standard power source.
FEATURES:
1. Able to test basic error, shunt running, start, standard error automatically and manually
in single-step of single/three phase, according to relative regulation of kWh meter.
2. Able to do change test caused by voltage influence, frequency influence and harmonic
influence.
Output of power source is speedy and stable, AC maximum output of each phase can reach 120A in
maximum.
3. Voltage, current and phase position of each phase can be adjusted in split-phase,
improving the flexibility of power source.
4. Frequency of each impulse input port can reach 40Hz.
5. 7-inch TFT color display touch screen, English menu, simple and convenient operation,
commonlyused functions and current basic load point can be controlled in one button.
6. Each meter position can provide one standard, dependent RS485 port, and able to perform
multi-function test, such as communication test.
7. Impulse port of each meter position, external polarity can be set randomly, able to adapt
kWh meter of impulse cascade and common-anode.
