[0002] Phase finders are mainly used for phase verification and phase sequence verification of power lines and substations. Phase finders transmit data wirelessly, process it, and then transmit it.

[0003] The prior art discloses a phase finder for determining line phase, disclosed in CN212301701U. The phase finder includes a reference phase collector, a signal processor, a receiver, a display, and a power supply. The phase finder is equipped with a phase detector. The reference phase collector is used to collect three-phase phase angle information from the local power grid and transmit this information to the signal processor. The phase detector is used to detect and transmit the electrical signal of the measured line. The signal processor processes and compares the information from the reference phase collector with the information from the phase detector and outputs the phase difference and phase information. The advantages of the present utility model are that the phase finder can directly determine the phase of the measured line, is simple to operate, has a fast detection speed, and is highly accurate.
