GF303 portable 3 phase ac voltage and current standard Electrical Power Calibrator with 63th harmonics output

GF303 portable 3 phase ac voltage and current standard Electrical Power Calibrator with 63th harmonics output 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.

Power calibrators and power quality calibrators GF333V2 - Three-phase Fully Automatic Test System with Reference Standard and Integrated Current and Voltage Source The Calmet GF303P portable test system consists of a three-phase reference meter of accuracy class 0.04% (or 0.1%) and an integrated three-phase current and voltage source up to 3x120A/600V

Split-phase power systems achieve their high conductor efficiency and low safety risk by splitting up the total voltage into lesser parts and powering multiple loads at those lesser voltages while drawing currents at levels typical of a full-voltage system. This technique, by the way, works just as well for DC power systems as it does for single-phase AC systems. Such systems are usually referred to as three-wire systems rather than split-phase because “phase” is a concept restricted to AC.

GF303 is electric AC/DC power and energy calibrator for calibration of power meters, power transducers, power quality analysers and generally all kinds of power measuring devices. AC voltage, current, power and energy functions have calibrated phase shift in frequency range from 45 Hz to 65Hz with resolution as good as 0.001 Hz.

As power grids get bigger and carry more power, the need for quick, reliable disconnection when faults occur becomes more urgent. The purpose of protective relay equipment is to sense fault states and trip circuit breakers. If a fault isn’t corrected early, personal injuries and damage can occur. Megger’s next generation of programmable secondary relay test systems are designed specifically to test microprocessor, solid state and electromechanical relays. New generation single phase and three phase test systems with remote control facilities and analytics software can make life much easier for protection test engineers.

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.
