Hot line detection system for high voltage switchgear - I ...Cited by: 18Publish Year: 1974Author: Horace A. HarveyA hot line detector for remotely monitoring conductors of switchgear apparatus which have a high voltage such as 15,000 volts; said switchgear apparatus including stationary metal cubicles having indicating circuit means thereon for indicating the energization of at least one high voltage conductor associated with said switchgear apparatus at a voltage in excess of a given voltage, said at least one high voltage[email protected]
Translate this pagePower industry high-voltage switchgear generally require the process of leakage inside and outside the work pressure can not be greater than 0.05Mpa, so the system uses the box filled with helium box leak detection way, the vacuum box and workpiece synchronization vacuum.Get Price
2020-4-23Mitsubishi Electric gas-insulated switchgear (GIS) and gas circuit breakers (GCB) represent the best of modern technologies. Since commercializing Japans first GCB in 1968, we have supplied a variety of circuit breakers and GIS rated from 72~1100kV.Get Price
2018-9-10their risk for a possible breakdown. For high voltage apparatus, the UHF(Ultrahigh Frequency) PD(Partial Discharge) detection technology has proven to be a sensitive method. In this contribution the development of UHF PD detection system for the MV switchgear and its application are described. Experimental studies show that the PD detection of the MV switchgearGet Price
