Based on the active sensing system of the switchgear office discharge sensor , the switchgear office discharge monitoring system carries out an all - round monitoring of the operating state of the equipment , realizes the status detection of the switchgear equipment , and the detection types cover UHF , ultrasonic , transient ground voltage and other types , so as to achieve the purpose of early fault prediction , which completely changes the traditional practice of relying on manual inspection and search in the past , and effectively prevents Fault , improve work efficiency .
