| Abstract: | Metal sheath of long cable lines can produce high induced voltage, which reduce the cable life and endangers the personal safety. Build the induced .voltage calculation model of three phase conductors to the metal sheath, derive the induced voltage calculation expression of the single-core cable metal sheath. |
