Multi functional three-phase nuclear phase instrument DYHX-8700

1、 Product introduction

DYHX-8700 multi-function nuclear phase meter (also known as wireless high-voltage phase sequence meter) (hereinafter referred to as "the instrument") is used to measure the phase sequence of three-phase lines and the phase difference between ABC, and can also be used for nuclear phase operation. The instrument is suitable for live working of 6KV~220KV transmission lines, and has the function of high voltage electricity detection.

The instrument adopts wireless transmission technology, which is safe, reliable and convenient to use. It is possible to directly measure the phase sequence of high-voltage lines. Conform to the relevant standards of national quality supervision, inspection and testing of power safety tools and instruments.
