An overview,

Our company adopts low-frequency zero-crossing carrier communication technology to develop a new generation of products zY-CT806A station area (line branch) identification instrument, to ensure no crosstalk in adjacent stations, strong anti-interference ability, communication distance to more than 3km. At the same time, pulse current detection technology is added. Current detection adopts zero-sequence pulse current method, which increases the number of branches that can be detected at the same time. Compared with phase line current detection, the operation steps are reduced. The instrument meets the requirements of detecting multiple line branches under the same transformer, and can detect 12 line branches at the same time
