Voltage measuring instrument GF211B

frequencycurrentpower factor

GF211B multi-function double clamp digital phase angle meter is a multi-functional portable instrument. It is an ideal choice for electric power bureau, factories, mine, petroleum-chemistry enterprises, metallurgy factories and so on. FEATURES Measure phase angle between two voltages, between two current or between voltage and current Measure alternating voltage (U), alternating current (I), frequency (F), active power (P), reactive power (Q), power factor (PF) and so on. Current signal is obtained by the clamp current transformer on line directly Discern inductive circuit and capacitive circuit; Directly read differential protection phase among every unit of CT Can check connection of transformer Measure two way voltage phase sequence Can check whether the meter connection is right or not Can evaluate the running speed of electric kWh meter High resolution of current, so can be used as a leakage current meter
