To find out Multiflying factor
1) If meter CT Ratio is not given then CT Ratio provided in
the panel has to be considered. Example if CT Ratio in the
Metering Panel is 600/5 then the M.F is 120.

2) If CT Ratio is mentioned in the Meter then Meter CT
Ratio / CT Rating Provided in the Metering panel.
Example If the CT Ratio of the Meter is 600/5 and CT
Provided in the Panel 800 /5 then Multiplying Factor will
be 600/5 /800/5. i.e., 600/800 then M.F is 3/4 (0.75)

3)In addition to this any Multiflying factor is mentioned
in the Meter then it has to be multiplied. Example if Meter
CT Ratio is 600/5 and Panel Ratio is 800/5 and M.F
mentioned in the Meter is 3 then the M.F will be (600/800)
*3. i.e., 0.75*3 =2.25

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)
