GF303B 8KG HIGH ACCURACY 3 PHASE ELECTRIC PORTABLE Electrical Power Calibrator FOR PROTECTION RELAY DEVICE
6.8KG HIGH ACCURACY 3 PHASE ELECTRIC PORTABLE POWER SOURCE FOR
PROTECTION RELAY DEVICE
GF303B 3 phase standard Electrical Power Calibrator is suitable for all the power supply company, electric power
company distribution network automation departments, is also
suitable for petrochemical, coal mine, railway and steel industry
etc, to power automation departments use.
The GF303B 3 phase standard Electrical Power Calibrator consists of an integrated three phase 6A current source and 264V
voltage source.
The 3 phase standard Electrical Power Calibrator is particularly designed for analysis of complete metering
installations and local mains conditions. The meter test bench
offers high functionality combined with an excellent menu guided
operation via built-in thirty keys and colored 7” touch
LCD-display.
The GFUVE Calibration GF303B Three Phase Electrical Power
Calibrator is the most cost-effective way to get the superior
accuracy and performance of three independent phases in one
instrument. It is an ideal solution for calibration laboratories,
electronics manufacturers, electric utility meter shops, and other
organizations that manufacture and maintain energy meters, power
quality analyzers, and similar tools.
A high accuracy AC and DC power calibrator suitable for calibrating
watt-meters, power meters, and kW-Hr meters. The instrument is
supplied with virtual control software allowing the user full
control via laptop or PC. Frequency can be set in 0.001Hz steps
from 40 to 70Hz, and phase in 0.01degree steps.
FEATURES
- Lightweight portable Electrical Power Calibrator: the integrated module, weighing 6.8 kg;
- The fastest output (10 ms): by high performance 32 bit CPU, the
frequency of 1.2 G;
- Stable fastest (1s): hardware PID, the output of the standard
resource without delay, fast response;
- With the strongest load, load regulation rate fast, single phase
with resistance sex load 15 VA; with pure capacitive load (0.33
uf);

harmonic;
- Stability, and the best, stability for 0.01% / min; English or
Chinese display.
- Two kinds of frequency output: but at the same time points in
different frequency voltage output; And amplitude can adjust
arbitrarily output;
- Powerful Software, the operation is simple, convenient, three steps
can complete verification;
- Debugging far move communication protocols, as many as 20 types,
covering domestic all factories statute;
- The fastest verification;
