GF211 ELECTRICAL DOUBLE CLAMP PORTABLE DIGITAL PHASE ANGLE METER WITH 10A CURRENT CLAMP
Application
Applicable to relay protection, electric power measure, electric power construction and conversion engineering and other professional, is the electric power department, factories and mines, the petroleum chemical industry, the metallurgy system for the secondary circuit check ideal electric meters.
Introduction
GF211 double clamp digital phase angle meter 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. The current signal is obtained by the clamp current transformer without cutting off current wire. It can discern inductive circuit and capacitive circuit; can directly read differential protection phase among every unit of CT; can check connection of transformer; measure three way voltage phase sequence; can check whether the meter connection is right or not; can 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 for electric power bureau, factories, mine, petroleum -chemistry enterprises, metallurgy factories and so on.
GF211 with high precision small clamps head to improve current precision measuring clamp, facilitate field wiring a dense environment is used.
