When a square wave is applied to primary of a transformer then what will be output wave form of se..

Answer / guest

It can be a quasi or true sinusoidal form, depending on i.
period of the signal generator, ii. and the time constant
of the transformer winding [ ie inductive circuit]. A
combination of these two would determine the shape of your
output wave form. A mathematical analysis would be helpful
to determine the exact nature of the shape of wave where

t = L/R and at any instant before t , e = E[e^R/L]

If you were to then to plot a graph from t=0 to t =T, the
you can observe that e would define a a quarter period to
peak, and if you then take off the the square wave, the
inductive energy stored having E as induced voltage, in the
transformer will exactly define a mirror image when it
discharges ie e = E {1 - e^R/L]

Answer / vikram

THIS IS CALLED PULSE TRANSFORMER.

IF INDUCTANCE IS HIGH THEN OUTPUT IS EQUAL TO INPUT.

IF L=LOW IT PRODUCES EXPONENTIALYY DECAY PULSES
IN BOTH +VE AND -VE CYCLES.

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.
