I found different articles about earthing of armour ,lead and sheild of power cable.I know that in single core power cable earthing from one side is prefered.what about 3core cabls(MV & LV),is it better to ground armor,lead and sheild in both side or one?approximate lenght of cables is 300m.
what are the problems,if single core cables are laid side by side position instead of trefoil,I need a clear refrence that calculate amount of eddy current that produce in side by side formation.
