What will happen if I apply DC to AC transformer? please
send detailed answer at habib_rahman_habib786@yahoo.com
Answer Posted / e venkat reddy
if u apply DC voltage to transformer,
reactive load whose formula is
Xl=2*phi*f*L
In pure dc the frequency is zero so inductive reactance is
zero and the resistance of transformer is very small ie .2
to .4 ohms. if u apply 230v DC then the current will be
230/.4= 575 amps so that it is going to burn winding of the
transformer. so we use transformer only for AC voltage.

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.

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How???
