GF303D 100A Three Phase Secondary Current Injection test equipment
for Energy meter or Power meter
(Accuracy class 0.05%/0.1%)
Application
GF303D 100A Three Phase Secondary Current Injection test equipment
for Energy meter or Power meter is suitable for power department,
measuring department, quality control department, research units,
institutions of higher learning, electric energy meter, power
distribution terminals, power supply management, load control,
power quality, reactive power compensation device and the
production of enterprise etc.
The GF303D is a powerful and portable three phase current and
voltage source. All test values are generated absolutely
synthetically with a high degree of accuracy and stability. The
source is available in 12 A, 24A or 120 A.
The GF303D Three Phase Secondary Current Injection test equipment is a lightweight and portable current and voltage source based on
newest technology and serves for solving this problem by simulating
the required load conditions. Operation is performed by integrated
7“ touch screen or via keyboards.
Features
1. 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.
2. To set 2-128 times of the amplitude and phase harmonics, and it
can be added to the base wave in every harmonic output.
3. Frequency value is adjustable (AB and phase C).
4. Voltage, current output a wide range, big power, high stability,
waveform distortion degree is small.
5. 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%.
6. To apply the 32 bit MPU + DSP + FPGA, powerful flexible.
7. To use hardware PID, fast response, the change of load will not
cause output volatility.
8. 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.
9. Range switching automatically
10. To use software calibration, simple operation, stable and
reliable.
11. To have big screen, 320 x 240 LCD display, Chinese or English
interface, operating simply.
12. To have perfect over-current, over-voltage, heat, a
shorts-and-opens, overload protection, failure detection
automatically.
13. With RS232 interface, and PC connection
14. To take place machine software, it can be output through the PC
software program.
