High Stability Portable Programmable Precision three Phase AC Electrical Power Calibrator With 0.5L 0.5C testing point

GF303D portable programmable three phase ac 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.

The GF303D electrical power calibrator can also be used to type test 0.1% to 2% energy meters. Choose the GF302D electrical power calibrator when you need the highest accuracy available for calibrating secondary standard meters, energy revenue meters and type test applications.

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.

The GFUVE Programmable AC electrical power calibrator model GF303D delivers pure, 4-wire, 3-phase AC power OR 3PW, 1P2W, 1P3W. Unlike the traditional 3-phase AC source, it includes low power rating models at very low cost. Users can program voltage and frequency, current, phase and angle, PF; measure the critical characteristics of the output on its LCD display.

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.

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.

GF303D Electrical Power Calibrator have 1P2W, 1P3W, 3P3W, 3P4W mode, it can be set to output from 0 to 120a current and 0 to 500v voltage.
