Application of Multi-measure Joint Precise Positioning in Cable GIS Terminal Partial Discharge Detection
Partial discharge detection technology is an important method for assessing the condition of urban high-voltage cables.The complex structure of cable GIS terminals and interference from the substation environment present challenges.A multi-measure combined detection approach,utilizing high frequency,ultra-high fre-quency,and ultrasonic methods,is proposed to identify the type of partial discharge.Through homology analysis and interference elimination,precise localization was achieved,providing a detailed reference for developing elimi-nation strategies.A case involving the accurate localization of a 110kV cable GIS terminal is illustrated to offer guidance for similar signal detection and location in cable GIS terminals.
