Digital Phase Meter

This digital phase meter is designed for field measurement of voltage, current and phase. It’s handheld, with high precision, low cost, and double channel input.

This Digital Phase Meter can be used to measure the phase between U-U, I-I and U-I in the field, distinguish the inductive and capacitive circuit and phase sequence of three-phase voltage, detect the wiring group of transformer, test the secondary circuit and the mother differential protection system, and read out the phase relationship between the CT of differential protection groups,check the wiring of the watt-hour meter, etc

The clamp current transformer is used to input the measured current, so there is no need to disconnect the measured line during the measurement.

When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, so that the short-circuit of the tested line caused by possible miswiring can be completely avoided, to avoid meter burning .

High contrast LCD screen, words up to 25mm, screen Angle can be freely converted to about 70°, to obtain the best visual effect.

The Digital Phase Meter shell is made of engineering insulating material and rubber anti-vibration protective cover, which is safe and reliable.
