Answer Posted / rajendra.s
no my friend,it depends on APFC relay,
1.in L&T make APFC relay ct is looped in R-phase.
2.in Sentron make APFC relay ct is looped in Y-phase.
3.in Sycon make APFC relay ct is looped in B-phase.
if you have any dout see all above relays wiring diagram.
For measuring PF APFC relay required any two phases & one CT sence on remaining phase from main PCC Phase.
Eg.(R-Y phase & BCT from Main Panel)
