Product Introduction
TAG-8700 Wireless High Voltage Phase Sequence Meter is used to determine the phase sequence of a three-phase line, as well as the core phase of a two-line grid connection or a ring network. The instrument is suitable for 5V~220kV AC transmission lines and secondary live display core phase, and has a line live detection function.
TAG-8700 adopts digital wireless transmission technology, which is safe, reliable, and easy to use. It is the first instrument to directly measure the phase sequence of high voltage lines.
