Spec. of one of the projects I am working requires that "Armour of all single core AC power cables shall be grounded at one end only”. I guess it is to do with circulating current but can't visualize real problems for power cables.
The project comprises of 6kV and 400V system and both systems are high resistance grounded.
Could some one please throw some light?
