■ Product overview
The distribution transformer station area identification instrument is composed of the host and the handheld extension and related accessories. The communication between the host and the handheld extension adopts low-frequency zero-crossing communication technology and pulse current detection technology, and the adjacent stations share high voltage, common ground, and common cable. In the case of grooves, the station area identification, phase identification, and branch identification can be accurately performed.
