PHASE ANGLE METER, DIGITAL PHASE ANGLE METER, HANDHELD DIGITAL PHASE ANGLE METER |
INTRODUCTION:
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
