CAN WE GENERATE AC WITHOUT DC EXCITATION?
Yes
By replacing the field winding with permanent magnets. The
problem with doing this is that the output voltage is
controlled only by the speed of the alternator. This means
that at constant speed (frequency)the voltage will fall as
the load is increased. If the voltage must be constant the
speed must be increased with load. So the frequency will
not be constant.

I want to ask a question which i faced during testing of Capacitive Voltage Transformer in AIS. We have measured the C1 , C2 individually , but when we start to measure the total C1+C2 , the testing equipment shuts down and says low loading. Kindly is it possible to find the total capacitance by using measuring device. kindly briefly explain the procedure.
