Study On The On-Line Monitoring System of the Insulation Quality of High Voltage Electric Power Equipment

This paper discusses the on line monitoring technologies of some electric parameters such as dielectric loss,divulging current,equivalent capacitance,running voltage.A kind of on line monitoring system of insulation capability which is based on monitoring the divulging current and dielectric loss of high voltage equipment is developed.The system has many merits such as helping people to discover the hidden problems of accident in time,to reduce power cut and overhauling and to improve security of power supply.
