As a partial discharge detection method mainly used for high-voltage switchgear equipment, TEV realizes the judgment and evaluation of the internal insulation state of the switchgear through the ground-wave partial discharge (TEV) sensor placed on the outer surface of the switchgear. Because it has the advantages of high sensitivity, non-contact and no radiation, it will not affect the operation of the switchgear, so it is widely used in the partial discharge detection of high-voltage switchgear.
Due to the extremely short rise time of the geoelectric wave, the method of partial discharge detection of the geoelectric wave can detect the discharge situation more quickly, so that people can take measures in a timely and effective manner. On the one hand, the partial discharge detection of ground radio waves has high sensitivity to the partial discharge inside the switchgear, and can accurately capture the weak discharge signal generated by it. On the other hand, the partial discharge detection of ground radio waves can realize the detection of the insulation state in the switchgear without direct contact with the equipment, which can ensure the safety and convenience of operation without affecting the normal operation of the switchgear, and this detection method will not produce any radiation, which is very safe for the environment and operators.
Geoelectric wave partial discharge detection is an efficient and safe detection method, which is of great significance for ensuring the normal operation and maintenance of power equipment. Shaanxi Public Intelligence for the operation status monitoring of the switchgear, the comprehensive intelligent UHF partial discharge, intelligent ultrasonic partial discharge, intelligent transient ground voltage partial discharge and other detection methods, can effectively obtain the state information in the operation of the switchgear, so as to find the insulation defects of the switchgear more efficiently and timely.
