how we calculate capacitor bank mvar for 11 kv distribution networ , and i need releation between capacitor bank with voltage, frequency, current, pf

I have a 1000 kVA Transformer(11kV/0.415kV) and a APFC panel of 400 kVAR(LT).Now if i want to remove the LT APFC panel and install a HT(11kV) APFC panel on the HT side is the HT APFC panel will work same as the LT APFC panel(improve the power factor),if yes what will be rating of the HT APFC panel?what is the formula to calculate HT APFC panel rating???

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)

If a generator of generating station produces 100MW rated output then what will be the rating of the step-up transformer connected to it?

3550

as we see that in our country the power rating for transmission is always rated in multiple of 11 like 11kv,33kv,66kv132kv. So i want to know wht is reason or logic here.
