a natural mineral oil is used as coolants.
now a days ASKARELS or PYROCLOR is widely used , since non
inflammable. high stability on di-electric . thermal
observation and so many advantages...

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)
