Design and Implementation of 110 kV Cable Insulation Online Monitoring System Based on Partial Discharge
With the improvement of power system voltage level,the reliability of cable insulation status has become an important factor to ensure the safe operation of power grid.Partial discharge is the key indication signal of cable insulation aging and defects.Using on-line monitoring of partial discharge characteristics can effectively predict and prevent the occurrence of insulation faults.A 110 kV cable insulation on-line monitoring system based on partial discharge is designed and implemented.Through signal detection,feature parameter extraction and fault location diagnosis model construction,the system achieves efficient and accurate insulation state monitoring and fault diagnosis,and improves the safety and reliability of cable operation.
