Q.Directional overcurrent relays have two exciting coils connected across 

  • ACT secondaries of two different phases.
  • BVT secondaries of two different phases.
  • CCT and VT secondaries of the same phases.
  • DCT and VT secondaries of two different phases.
Correct Answer : (C)

CT and VT secondaries of the same phases.

Hints :

Directional overcurrent relays have two exciting coils connected across CT and VT secondaries of the same phases.
