LCD 25VA RS232 TFT 500V Energy Meter Testing Equipment

Laboratory Three phase phantom load of testing energy meter for portable meter test equipment

This 3 phase phantom load is used for energising either CT or Direct connected Energy meters during commissioning or routine testing. The GF302D1 can deliver over 50VA per phase at 100Amps / 0.5V. "Variacs" are used to adjust the current injection level from zero to full scale. Each phase has a dedicated display showing the voltage and current value.
The phantom loading is used for examining the current rating ability of the energy meter. The actual loading arrangement will waste a lot of power. The phantom loading consumes very less power as compared to real loading, and because of this reason, it is used for testing the meter.
Three Phase Voltage And Current Phantom Load GF302D1 - Beijing GFUVE Electronics Co. Ltd. Suited to heavy duty workshop testing of meters up to 150A or 200A, this Model is conveniently housed in two separate voltage and current units. Voltage unit: The unit is powered from a 3 phase 4 wire 220/380V supply.
We hold expertise in developing a wide range of exemplary Three Phase Test Benches. offered range comprises Three Phase Phantom Load Test Bench and Three Phase Meter Test Bench. offered products are manufactured by making use of supreme quality required basic material, in complete adherence with the defined parameters of the industry.

FEATURES

To set up and take the load regulation of voltage, current, phase angle, frequency and power factor, also can be used as AC current source, AC voltage source or power source.
To set 2-128 times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output.
Frequency value is adjustable (AB and phase C).
Voltage, current output a wide range, big power, high stability, waveform distortion degree is small.
Strong with load ability, but it can take capacitive, sensibility, resistance of composite type load or load and load regulation is higher than 0.01%.
To apply the 32 bit MPU + DSP + FPGA, powerful flexible.
To use hardware PID, fast response, the change of load will not cause output volatility.
Industrial frequency waves as high as 50000 points a week of the wave kneading, signal output without filter, precise output waveform, the harmonic output precision, harmonic distortion degree is small.
Range switching automatically
To use software calibration, simple operation, stable and reliable.
To have big screen, 320 x 240 LCD display, Chinese or English interface, operating simply.
To have perfect over-current, over-voltage, heat, a shorts-and-opens, overload protection, failure detection automatically.
With RS232 interface, and PC connection
To take place machine software, it can be output through the PC software program.
