What will hapen if we run generator below 47.6hz frequency?
Answer Posted / a.mishra
According to Alternator voltage eqn., MAX.FLUX is inversly
proportional to FREQUENCY. If we reduce the frequency,then
max. flux will increase and the problem of core saturation
may happen. Other problem of iron losses will increase in
that alternator as well as the system equipments connected
to that source like Transformers,induction motors.

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
