GF333B 120A 480V 0.02% Three Phase Portable Energy Meter Testing Equipment
3ph portable energy meter testing equipment
(accuracy class0.05%)
Product Description
It is a portable standard to test three phase meters and single phase meters, designed to work in the field or in the laboratory.
GF333B three phase reference standard is a portable reference standard meter used to test three phase meters and single phase meters error, it designed to work both in the field and in the laboratory. The GF333B reference meter is used to measure three phase AC energy and voltage, current, power, phase angle and other parameters in lab, and it also can be used to integrated in the energy meter test system and supply the standard energy pulse and every measurement parameters.
