Specifications
This test equipment is used for grid corporation of measurement and test centerApplication of Meter test equipment GF302D Portable Three-Phase kwh multimeter calibrator ,with excellent working Performance,CE,ISO9001:2008,IEC approved,english version display,with two years quality warranty.
This test equipment is used for grid corporation of measurement and 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 standard power source.
Features & Functions
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/DC 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.
* LCD in color and big screen, complete Chinese 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 do multi-function test such as communication test.
* Each meter position can provide six-pulse input port, able to connect active power pulse, reactive power pulse, clock pulse, finishing the whole test process automatically, solving the problems of changing pulse line.
* Impulse port of each meter position, external polarity can be set randomly, able to adapt kWh meter of impulse cascade and common-anode.
