TEV Sensor

      The TEV sensor developed and designed by our company is simple in structure and small in size, which is convenient for on-site installation and debugging of various electric power monitoring devices. The TEV sensor is installed on the surface of the cabinet with an adsorption design, and is connected to the measurement equipment at the back end for processing and transmission (including filtering, wave detection, digitization, identification, remote transmission), so as to conduct online or patrol monitoring of operating electric power equipment.

    Partial discharge (PD) is one of the faults that occur due to the defects of the user’s electrical high-voltage insulation system. The user needs partial discharge measurement to monitor the equipment condition and avoid faults. The partial discharge signal in the metal cabinet (switch cabinet) is usually an electromagnetic wave with a wide bandwidth, which usually generates a weak surface current on the surface of the metal cabinet during the transmission process, and the instantaneous grounding voltage will be generated due to the non-uniformity of the surface materials. TEV sensor uses this principle to measure discharge signal.
