The series of wireless high voltage core phase devices produced by our company are mainly used in phase calibration and phase sequence calibration of power lines and substations. The main functions include electric inspection, nuclear phase, phase sequence measurement, etc.This product adopts double shielding and new digital circuit, with strong anti-interference, fully meet the requirements of EMC standard, adapt to various electromagnetic field interference occasions.
The high voltage phase signal of the measured conductor is directly transmitted after processing, and then received by the handheld computer for phase comparison, so as to qualitatively evaluate the result after the core phase, and display the phase Angle difference and vector graph in real time.
This series adopts wireless transmission technology, truly safe, reliable, fast and accurate, different voltage levels (10V-500KV) are applicable.When checking the structure of the grid, the relative phase of different conductors can be accurately identified for the three-phase connection of the line, and there is no electrical connection between the two measuring components, which makes the application of the measuring device very flexible and safe.
