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.

It is feasible lower current.It also transfer input waveform to output.

In domestic supply, when neutral touches earth the earth leakage trips. Does this mean that if the star (neutral) point of an alternator is earthed that power will flow to earth i.e. a direct short to earth?

What happens if the secondary of the transformer is shorted?
I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
