GF302D Portable Three Phase kWh Meter calibration equipment, with
accuracy class of 0.05%,
high stability, english version display, two years quality
warranty.
(Accuracy class 0.05%/0.1%)
Application
The Portable Three Phase kWh Meter calibration equipment is used
for grid corporation of measurement and energy test center,
management department of power supply bureau, national energy
measurement of testing authorities, and also used to test each kind
of single/three phase kWh meter of industries and mining
enterprises as well as electric meter manufacturers. Meanwhile, the
calibrator also can be used as one high precision standard power
source.
Features
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.
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.
Voltage, current and phase position of each phase can be adjusted
in split-phase, improving the flexibility of power source.
Frequency of each impulse input port can reach 40Hz.
7-inch TFT color display touch screen, English menu, simple and
convenient operation, commonly used functions and current basic
load point can be controlled in one button.
Each meter position can provide one standard, dependent RS485 port,
and able to perform multi-function test, such as communication
test.
Impulse port of each meter position, external polarity can be set
randomly, able to adapt kWh meter of impulse cascade and
common-anode.
