HUAYI - Model TAG-8700 -Wireless High Voltage Phase Sequence Meter for Power Lines
The TAG-8700 Wireless High Voltage Phase Sequence Meter by HUAYI is engineered to accurately determine the phase sequence of three-phase lines and core phase in two-line grid connections or ring networks. Suitable for AC transmission lines ranging from 5V to 220kV, it utilizes advanced digital wireless transmission technology to ensure safe, reliable, and intuitive operation. The device notably features a 3.2-inch color screen, displaying phase differences, vector diagrams, and in-phase results, with a line-of-sight transmission range of approximately 100 meters. The TAG-8700 is equipped with built-in rechargeable lithium batteries for both the transmitter and receiver, a 10440 lithium battery in the transmitter, and an 18650 lithium battery in the receiver, facilitating extended use and easy maintenance. Additional features include a hand-held receiver that displays crucial operational parameters and an automatic shutdown function following one hour of inactivity, optimizing battery life. This specialized meter is an essential tool for effective phase analysis and monitoring in high voltage applications.
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.
