How to Use a High-Voltage Wireless Phase Verifier

When contacting a live wire, an audible signal is heard and 4 indicator lights turn on. After 5-10 seconds, LED2-4 turn off and the audible signal stops. The transmitter is set to work for 5-10 seconds during voltage measurement, after which it automatically enters phase measurement, with only one LED indicator lit. If the audible and visual signals do not stop after 5-10 seconds, the battery is low and needs replacement. To measure another phase, detach the transmitter from the line, wait until LED1 turns off, then place the transmitter on the line for another voltage measurement. Repeat as above.

    When entering measurement mode, the transmitter emits radio frequency signals into the air, and part of the signal is transmitted along the line acting as an antenna. Once the receiver recognizes the signal, it immediately starts working.

    The wireless phase verifier is a dedicated device used to check the phase sequence of high-voltage power lines and large equipment such as transformers before installation and operation. The PSWHX wireless high-voltage phase verifier has replaced the previous contact measurement method, eliminating the danger of contact measurement and ensuring the personal safety of measurement personnel. The measurement method is simple and the results are reliable.
