GF211D digital phase angle meter & phase angle voltmeter
GF211D multi-function double clamp digital phase angle voltmeter is a multi-functional portable instrument. It can measure not only alternating voltage, but also alternating current. Its important function is to measure phase angle between two voltages, between two current or between voltage and current. Currents up to 20A and voltages up to 600V. The current signal is obtained by the clamp on ct without cutting off current wire. It can discern inductive circuit and capacitive circuit; directly read differential protection phase among every unit of CT; check connection of transformer; measure three way voltage phase sequence; check whether the meter connection is right or not; evaluate the running speed of electric kWh meter. It has high resolution of current, so can be used as a leakage current meter. It is an ideal choice of test tools for electric power bureau, factories, mine, petroleum-chemistry enterprises, metallurgy factories and so on.
