Non Contact Phase Rotation Meter, AC 70V~1000V, Φ10mm~Φ40mm

Clamp Details

Q1: How does a phase tester work?
A1: When the phase tester is working, the digital signal is sent to the receiving end through the wireless sending module, thereby reducing the interference and error, and greatly improving the working performance of the phase tester. When the phase detector is in use, first hang the transmitter on the conductor of the power grid under test, and then touch the receiving device to another grid conductor to be tested.

Q2: Functions of Phase Detectors
A2: sisco Phase Detectors can perform phase sequence detection (positive phase, anti-phase, default phase), live line inspection, simple electrical inspection, fire line identification, default phase judgment, broken line location search, DC line breakpoint detection, and line maintenance.

Q3: Why do you need a phase tester?
A3: If AC power supplies with different phases or phase sequences are paralleled or closed, a large current will be generated, which will cause damage to the generator or electrical equipment, so a phase detector is required for measurement.

Phase verification refers to the use of a tester or other means to check whether the phases and phase sequences of two power sources or loops are the same in the electrical operation of the power system, which means the measurement of the phase difference in the actual operation. Newly built, rebuilt and expanded substations and transmission lines, as well as after the line is overhauled and before power is sent to users, must conduct three-phase circuit phase verification tests. Therefore, a phase tester is required.

Tips for using a phase rotation meter

1. When using the phase rotation meter, no other power source or battery is needed to power it, but it can be powered directly by the power source under test.
2. Most phase sequence meters have the function of phase loss indication.
3. The insulated jaws of the phase rotation meter can be used to clamp and detect insulated wires with a diameter of 10-40mm.
4. When using the phase rotation meter, if one of the three-phase input lines is connected to electricity, the phase meter will be charged, so we must cut off the power before opening the case.
