In order to improve the limitations of the traditional high-voltage transmission cable fault analysis method,this paper proposes a method to analyze the whole life operation and maintenance cycle of high-voltage transmission cables from putting into operation to fault return,comprehensively analyzing cable faults from the aspects of cable joint manufacturing process,field operating environment,operation and maintenance detection data and post-fault test detection.This method is used to analyze a real cable fault case in North China from multiple angles.Through tracing the root cause of the fault,the results show that the method is effective and can provide reference for the analysis of the same type of fault.
