(Accuracy 0.5%)
Application
GF211B Handheld 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.
Phase-Angle Meter. an instrument used to measure the cosine of the phase-shift angle, or the power factor, between voltage and current in electric AC circuits at frequencies specified for mains used by industry or to measure the phase difference of electric oscillations.
Phase angle meters measure magnitudes AND angles based on a reference angle. Can you guess what the phase angle meter would measure in the following figure? The phase angle meter would measure 100V, but the angle will be a random number that might change constantly because the phase angle meter does not have a reference.
Phase-Angle Meter. The measuring mechanism in such meters is a ratio meter of the electrodynamic, ferrodynamic, electromagnetic, or induction type; the deflection of the moving part of the ratio meter depends on the phase shift between the given voltage and current. Electronic counters are used as phase-angle meters for a wide range of frequencies.
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
Phase angle meter. It is capable of displaying the phase angle relationship between two power signals, which can be two currents, two voltages or any combination. Currents up to 10 A and voltages up to 500 V can be applied directly to the instrument. The current input range can be extended by using external current transformers.
