Answer / bhavneet
The transformers are generally dI/dt modules but where in
there is requirement of transformers in switching the sudden
change in current offers very high inductance, which can
distort the output waveform. If the input square wave the
output might be distorted to trapezoidal forms or can have
transients going back into the input line also, as in case
of inverters. A pulse transformer is very very low on
hysteresis and can transfer almost 1:1 input waveform to
Output. Also thereby eliminating any time lag in the
pulse.Its feasible for lower currents but for higher
currents its very very expensive to produce.

In a company the lines carrying 33KV but the load is below 10000Volts so we know that <11KV we can put 11KV lines but the lines are 33KV,..so how we can step down the voltage to 11KV with out erecting a substation
Dear All, I am new in construction company , my boss ask a question at time of interview , If we have 60MW generation and Single Power Transformer step-up we have. if CMR 50/60MVA , ONAN, ONAF respectively , is it sufficient or not ? for that much power to transfer,

Where we can use 3.5c cables instead of 4c cables.Why?
A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
