power 148kw i need exat cable size in 148 kw in 3phase what
size of cable can i used.

Answer Posted / mahendran

1 kw = 2 amps ie 148*2=296 amps

240 sq mm will carry 220 amps you make 2 * 240 =480 amps
this is actual amps for safety we give 755 load to the cable so
240*75%=380amps

150sqmmwilltake 180amps ie 2*180=360amps75%load
360*75%=270amps its less then your load

so you can select 2*240 sqmm cables

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)
