Apfc panel calculation depends upon building over all load ex .. Escalator 6 floor power formula p=i×v×1.732÷1000 assume A=17 3phase v=415 apply the formula p=12.21926 convert the kW ×1000 12219.26kw. It is convert by HP divided by 0.746 ans 16.3 6 floor 16×6 96 HP capacitor is inductiveload so 1÷3 96÷3= 32 kvar
