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)

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?
