Answer Posted / ashish rai
First of all of you notice that p=vi* cos(phi)
Another thing is that for running ac system 10% of voltage
fluctuation is allowed from electricity board.
Hence V is nearly constant factor.
I*cos(phi) is the variable factor hence with variation in
current power factor of system will change not voltage.
If any body is making wrong it plz clarify it.

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.
