Product Details
■ Product Overview
This system consists of an internet-based fixed-phase base station. ( Abbreviated as “base station” ) Handheld device with internet connectivity ( Abbreviated as “handheld device” ) Consists of two parts .
The system employs base stations to provide unified coverage of the phase‑reference standards within the designated area. , During the phase-locking process , The handheld device requires only a single fruit collection. , It can then be determined that the collected line belongs to A 、8、 C Which phase in the three-phase system? , Solving the current transmission issue / The issue of inconsistent phase-color coding on distribution lines.
The base station is installed at 220V/380V At the power supply, its phase signal is acquired and calibrated to the specified value. 10kV Line , Of this line A 、 B 、 C The three phases are defined as reference phase signals. The base station transmits the reference phase values to the handheld device via the mobile internet, and the handheld device compares its own measured phase values with the reference values, enabling rapid and accurate identification of the corresponding phase.
