In all the generators, the excitation supply is DC. What is
the significance of DC excitation? What will happen if AC
supply is given as excitation supply?
Answer Posted / vikas
If we give ac supply the function of the motar remains same
but the thing is that as ac voltage depends on frequency
eddy current losses increases.This can be eliminated by
laminating.

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.
