Application of Online Monitoring System of Partial Discharge in GIS Based on Ultra High Frequency Method in 1000 kV GIS
The Operation and Maintenance of UHV substation main equipment is facing more serious problems than EHV substation,once happening the equipment failure will bring great loss,so the safety and reliability of UHV substation main equipment is specially in need of attention.An online monitoring system of partial discharge in GIS based on ultra high frequency method is introduced in this paper,it can be real-time monitoring the discharge of fixed particles,unbound particles,floating electrode and insulation defects,accurately reflecting the state of 1000kV GIS.It is a great help to 1000kV GIS operation and maintenance.
