Directional over current relays have two exciting coils connected across
A)CT secondaries of two different phases
B)VT secondaries of two different phases
C)CT and VT secondaries of same phases
D)CT and VT secondaries of two different phases

Question

Quizplus · Accepted Answer

Directional overcurrent relays use both current and voltage inputs to determine the direction of fault current. The CT provides the current input, while the VT provides the voltage input, both from the same phase, to ensure accurate directional sensing.
