which fault current is maximum: 3 phase short circuit, LG, LL or LLG?? why?? in one of the problems that i have solved, 3 phase short circuit current on an unloaded generator came out to be less than the LG fault current. can anybody please explain why.

What is the basic of DTH.
Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
