Grounding Method Of Single-core Cable Sheath End Why A Along The Parallel Laying Of The Cable Must Be Installed In The Return Line

Metal sheathed end of cable lines, to ensure that the induction voltage does not exceed the allowed standard sheathing, you must install a parallel along the cable line laying conductors and grounded at both ends of the conductor, the conductor called the return line. While single-phase grounding fault, ground short-circuit current can flow through the return line back to the system's center point, through the return line of the ground current magnetic flux produced by offsetting a portion of the cable wire grounding currents generated by the magnetic flux, which can reduce the sheath fault induced voltages.
