Product introduction
The wireless high-voltage polarity tester (hereinafter referred to as the "instrument") is used for the phase comparison of two highvoltage lines for parallel or ring network connection. It can also be upgraded to have the function of remote phase comparison. The instrument is suitable for live working on 220V 220kV AC transmission lines and live working on the secondary side, and has the function of high-voltage test.
The instrument adopts wireless transmission technology, which safe and reliable to operate, easy to use, and overcomes many disadvantages of the wired polarity tester.
Working Principle
The instrument consists of 2 transmit and 1 receiving main unit. The transmitter can judge whether the line is live, and measure the phase and frequency of the line. Each transmitter sends the measured data to the main unit through radio, and the receiving main unit calculates the phase difference between the two lines according to the transmitter data, and judges the same and different phases
1. Real-time voice prompt of the measuring result and operation steps.
2. The screen displays 2 lines of phase difference, frequency, diagram, and same/different phase result at the same time.
3. Automatic shutdown without operation for 30 minutes.
4. The transmitter and receiver are both builtin rechargeable lithium batteries, and the battery is detachable and replaceable.
5. The battery capacity of the main engine is 2500mAH, the battery capacity of the transmitter is 450mAH.
1. Phase difference accuracy: error ≤ 5°.
2. Frequency accuracy: ±0.1 Hz.
3. The measurable range is 220V to 220kV.
4. The maximum transmission line of sight between the transmitter and the receiving host is about 100 meters.
5. Leakage current < 10uA when measuring high voltage.
6. Transmitter working power consumption < 0.1W, receiving working power consumption < 0.3W.
7. Working environment: -35℃--- 45℃ Relative humidity ≤ 95% RH.
8. Storage environment: -40℃--- 55℃ Relative humidity ≤ 95% RH.
9. Overall weight: about 5kg.
10. Instrument packaging dimensions: length 71cm* width 26cm * height 11cm.
