Webscheme. I. INTRODUCTION Breaker failure protection is an important component of comprehensive system protection. Given tight stability margins and the opportunity for equipment damage during fault current conditions, a breaker failure scheme is needed to avoid delayed fault clearing from backup and remote overreaching protection elements. WebMar 1, 2013 · breaker failure scenarios are much higher than switchgear busbar faults. The benefit of serving the backup protection and breaker failure protection for feeder faults in the same rough balance scheme should outweigh its relatively slower busbar fault clearance time as compared with other busbar protection schemes elaborated below. 3.
