Question

For the system below, the fault at F produces different responses at various times: R1 thru R6 are protection relays and CB1 thru CB6 are circuit breakers. Relay systems act as backup and remote backup relay systems. If R1, CB1, R6, CB6 R5 & CB5 operated, then the following is true: Select one: a. Loss of security of R4 b. Loss of security of R3 c. None of these d. Loss of security of R2
