Abstract :
SELECTIVE OVERCURRENT trips applied directly to large air circuit-breakers have sensitivity and accuracy approaching that of a relay, coupled with the robust construction required to withstand the shock and vibration of circuit-breaker operation. These requirements presented problems which had to be solved before satisfactory service could be obtained.
