IV. Power cable fault testing program
By applying the HM501A flashover instrument to locate the cable fault following procedures are generally required:
(1)Analyze the cable fault characteristics and learn about the cable rated voltage and the insulation materials.
   (2)Using the HM 501A Power cable Flashover instrument's impulse method to detect the cable length, and also to calibrate the radio wave speed in the fault cable.
   (3)By selecting the suitable testing method, applying the HM 501A Power cable flashover instrument to pre-locate the cable fault.
   (4)to pin point the power cable fault precisely, include the underground cable route, depth and the fault point locating.
(5)Applying the tolerances analysis method to the cable fault testing results(measuring tolerances transferring speed tolerances judgments tolerances instrument tolerances)
