Voltage is halved and also the current drawn by the capacitor bank. The rating will be 750/4 kvar

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???

We have 11kV/110V three phase indoor potential transformer in 66/11kV Sub-station, where the failure of PT is frequently happening and the rating of the PT is 0.2 class accuracy, with primary star and seconday (two cores) star connected. Some experts has suggested to not to connect the PT Primary neutral to the ground because when transformer neutal NCT connection is loose; the faulty current will flow through the PT primary neutral, resulting into failure of PT. My question is: Is it necessary to remove the primary neutral connection of the PT from ground? if not, what would be the reason for failure of PT. Please guide me.
