■ Product Overview

▲ vs-2601 Internet phasing system (hereinafter referred to as "system") consists of two parts: Internet phasing base station (hereinafter referred to as "base station") and Internet phasing handset (hereinafter referred to as "handset").

▲ the system unifies the phasing standard in the coverage area through the base station. In the phasing process, the handset only needs one acquisition to determine which phase of the collected line belongs to three phases a, B and C, so as to solve the problem of chaotic phase color marking of the current transmission / distribution line.

▲ the base station is installed at the 220V / 380V power supply, collects its phase signal, calibrates it to the designated 10kV line, and defines the three phases a, B and C of the line as the reference phase signal. The base station sends the reference phase value to the handset through the mobile Internet. The handset compares the phase value measured by itself with the reference phase value, which can quickly and accurately identify the corresponding phase.
