what is the reason for balance of voltage in magnetic
balance test?
Answer Posted / msalam_shahin
because the flux cuts the voltage with the adjescent limbs.
say if we apply voltage in r-n leads of star connected
secondary then we can get almost 80% voltage in y-n lead
and 20% VOLTAge in b-n leads. Because the b-phase is far
away from y-phase from r-phase.... this the reason.....

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)
