Abstract :
The paper describes how reliability models can be used to analyse the dependability and security of the main protection schemes used on a transmission feeder. Dependability is defined as the probability that when a fault occurs on the protected feeder, the protection system will operate and instantaneously trip the circuit breakers at both ends of the feeder. Security is defined as the probability that the protection will remain inoperative for all other fault or nonfault situations
