The YNTAG-8800 remote wireless high-voltage phase verification instrument is used to check whether the high-voltage phases are in phase at a distance (300 meters to 800 kilometers apart) and whether the phase sequence color is correctly marked. It can also be used for short-distance grid connection or ring network core phase. The instrument is suitable for live work on 5V～220kV power transmission lines and live work on the secondary side, and has a high-voltage electrical test function.

The transmitter can determine whether the line is live, measure the phase and frequency of the line, and send the measurement data to the host. The host will measure at the same time after being timed by GPS. The phase difference between the two hosts is calculated as the phase difference between the two lines, and the two lines are the same or different. phase.

The core of the measurement principle of the instrument is the time difference measured by the two mainframes synchronously. The time difference between the two mainframes is synchronized with GPS time service, and the synchronization difference is less than 10 nanoseconds. The phase error introduced thereby is less than 0.1 degree.

The instrument adopts wireless transmission technology, which is safe and reliable in operation, convenient to use, and overcomes many shortcomings of wired phase nuclear devices. And using GPS timing technology, two (or more) instruments can be separated by several hundred kilometers.
