XW-816 Phasing Device Unit / Wireless High Voltage Phasing Tool
About the product
The phasing unit for MV overhead distribution circuits is used to detect the high-voltage power grid closing point, on both sides of which the phase sequence is the same. Two power line connection before must check phase sequence, or the line may be short circuit. The instrument is suitable for 36KV power transmission lines and can test whether the line is charged. The Instrument adopts wireless transmission technology, safe and reliable operation, easy to use.
Working principle
The instrument consists of two transmitters (x and y) and a receiver. The two emitters can be judged whether line charged, and launch phase signal. The receiving meter receives the two emitters’ signals to judge whether the phase sequence is the same on both sides.
Security matters
- Insulating rod before using should be voltage withstand test.
- The standard configuration insulating rod length is 3 m, corresponding voltage for ≤ 220 KV. If the measurement circuit voltage higher than 220KV, please use the length of more than 3 meters of the insulating rod.
- Operation hand position not more than insulating rod handle position.
Technical characteristic
- Accuracy: When the phase sequence is same, the error≤ 5 °.
- The frequency accuracy：±0.1HZ.
- Measuring voltage range is 36KV .
- The transmitter and the receiving host transmission distance is more than 130 meters, the maximum distance between the two transmitters is about 260 meters.
- Results (in phase, interphase) using A standard, phase difference acuity ≥30 ° for out phase, the phase difference < 30 ° are in phase.
- Human voice prompt, male voice “in phase”, female voice “phase-out”.
- Screen shows two lines at the same time of phase difference, frequency, waveform and the vector diagram.
- The host shows battery, half an hour without automatic shutdown operation.
- Two emitter and receiver use rechargeable lithium batteries.
- Has a high-pressure test report and the function of the phase sequence.
- High pressure when measuring the leakage current < 10 uA.
- Transmitter power consumption < 0.1 W; receiving host working power consumption < 0.3 W.
