As shown in figure "A" of the illustrated ground fault occurring in a solidly grounded distribution system, what statement is true concerning the operation of the ground fault relay? See illustration EL-0128.
A
The ground fault relay contacts are normally open and close only when the motor individual line currents are unbalanced due to the ground fault.
B
The ground fault relay contacts are normally closed and open only when the motor individual line currents are unbalanced due to the ground fault.
C
The ground fault relay contacts are normally open and close only when the overall motor line current is high due to the ground fault.
D
The ground fault relay contacts are normally closed and open only when the overall motor line current is high due to the ground fault.
