& Current Source
Three Phase Portable kWh Meter Test Equipment with Voltage &
Current Source
The GF302D1 three phase portable kWh meter test equipment consists
of an integrated three phase current and voltage source(up to
500V/120A or 500V/20A) and built-in three-phase electronic
reference standard of accuracy class 0.05%. Characteristic features
of the GF302D1 are its wide measuring range, high accuracy and high
tolerance to unwanted external influences. The equipment offers
high functionality combined with an excellent menu guided operation
via built-in keyboards and colored 7” touch LCD-display.
GF302D1 portable test equipment adopts mature signal synthetic and
advance power amplifier technology, wide voltage and current output
with high efficiency and high stability, to be widely used in lab
and field.
APPLICATION
It is suitable for power department, measuring department, quality
control department, research units, and institutions of higher
learning, and electric energy meter, power distribution terminals,
power supply management, load control, power quality, reactive
power compensation device and the production of enterprise etc.
FEATURES
- To set up and take the load regulation of voltage, current, phase
angle ,frequency and power factor etc; as a large current source,
voltage source and power source
- To set 2 ~ 31 times of the amplitude and phase harmonics, and it
can be added to the base wave in every harmonic output
- 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 + CPLD, powerful flexible
- To use hardware PID, fast response, the change of load will not
cause output volatility
- Industrial frequency waves as high as 5000 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
- Display of vector diagram, adjustable to IEC387 OR DIN410
- Big touch screen, 7-inch TFT color LCD display, 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
