CA 2412151

A method for the protection of double circuit electrical power lines (IL-1, IL- 2) protected by local and remote circuit breakers (BS1, BS2, RR1, RR2, BR3, BR4, BR5). The method is performed by a local protection apparatus (RS1/RS2 or RS12) and comprises sensing electrical quantities measured at the local end of both circuits of the double circuit lines, monitoring the sensed electrical quantities to detect occurrence of a fault (F1 or F2 or F3), delaying operation of the local circuit breakers (BS1, BS2) on both circuits (IL-1, IL-2) for a time period sufficient to allow detection of operation of a remote circuit breaker (BR1, BR2 or BR3, BR4, BR5) by its effect on the electrical quantities on both circuits, and if the effect of a fault on a circuit of the double circuit line persists after remote circuit breaker operation, triggering operation of a local circuit breaker (BS1 or BS2) to isolate the fault.
