Yes, if the system was purely resistive, where is the reactive current
limiting.

My understanding of PF correction is to bring the system to unity, ultimately
using PFC's to create a net reactance of zero (Xl = Xc) where reactive power =
real power. Assuming a pig used PFC's that actually brought the PF to very near
1, how would we limit current? Purely resistive methods? Maybe this explains
why pigs use inductive current limiting? Not sure, just thinking here.

Thanks Terry. I'll load it up.
