A phantom load is any electricity that an appliance or device
consumes even when it’s turned off. These phantom loads, also
commonly referred to as vampire loads, can be small for individual
appliances but will add up quickly over the course of the month or
year.
GFUVE Electronics is a leading manufacturer of electronic energy
phantom load power source in China. We supply stationary or
portable test equipment, power sources, reference standards, Electrical Power Calibrator, relay test set, ct pt analyzer etc.
The new GF303D portable three phase phantom load stable Electrical Power Calibrator, designed from new digital wave compound technology and according
to International Standard, is newly intelligent equipment for
energy meters.
Three Phase Programmable Phantom Load. The instrument is used for
the calibration of high accuracy signal source in power system. And
it is mainly applied in utilities, Measurement Bureaus, Quality
Control System, Science & Technology Unit and Manufacturers for
energy meter, terminals, load control, power quality analysis ...
The GFUVE Calibration GF3031 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.
The GF3031 AC Electrical Power Calibrator is equipped with RS232
PORT as standard communication interface to control external
devices remotely. Power Factor Validation Power factor is an
important element when users judge the efficiency of a device.
FEATURES
