I have a transformer whose primary operates at 230V, 50Hz
for which the secondary voltage will be 12V, 50Hz. What
will be the secondary voltage if the primary is fed with
400V, 8KHZ Signal?

Answer Posted / anshul rawal
3/23volts or appro .13 volts. assume xmer to be ideal one
with no resistance in windings,nohysteresis loss etc, at
80khz the frequency is 160 times 50khz ,so current in
primary is 160 times less than at 50hz as inductive
reactance of primary ,ie 2 pi f l is 160 times more. as
current is 160 times less so is magneti flux in core,and so
is induced emf in secondary. if hysteresis loss and eddy
current loss r considered , then it is even less

if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.
