The grounding problem of Medium and Low-voltage power cables

In the public medium and low-voltage power cable networks, since the three-phase load is not equal, if using a cable with metal layer, the grounding problem of metal layer must be considered and the normal induced voltage at any point of the metal sheath (non-grounding) could not exceed 100V must be ensure.
