GDYB-S6 Three Phase Energy Meter Test Bench
6-position Meter Test Bench (Three Phase)
● Compact design, the meter rack of the testing equipment and the desk frame are all made of special aluminum alloy and the desk face-plate is made of fireproof and heatproof fiber material.
● Easy to use, both keyboard and PC operation are available.
● Advanced automation. User only needs to put on meters, adjust the photoelectric sampler and set the parameters in good condition, then all the test items, including pre-heating, actuation and false actuation tests, standard deviation test, basic error test are controlled by PC by one test. The procedure of meter calibration can be user-defined.
● Photoelectric sampler can realize three-dimensional adjustment. It can not only sample the turn-plate signal of the rotary meter but also receive the strobe signal of the electronic meter.
● The error processing system can receive signal from the photoelectric sampler and output pulse of the insert type electronic meter, and high frequency pulse signal of standard meter.
● Meters in same type(same phase line, rated voltage, calibrated current) but different constant (at most 3 kinds) can be test at same time.
● Test RS485 communication function of multi-functional meter, required error and clocking error is optional(Time signal output is necessary).
● Locate the mark area of rotary meter automatically, which enables easier false actuation tests.
● Superimposing 2 to 21 harmonics in fundamental wave of power frequency, harmonic amplitude and phase can be set according the requirements. Also harmonic analysis and draw waveform can be performed for output components.
● Auto testing on every unit voltage, current, power stability and three phase total power stability.
● High stability and reliability, which can provide strong output power. Voltage (current) loop can take load of any type.
● The testing equipment is provided with complete malfunction checking, locating, protecting and alarming functions to avoid damaging of the bench resulted from wrong manual wiring or operating.
● PC software provides complete functions, such as report printing, quantity counting and assets maintaining
