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. WebProtection schemes for lines, transformers and generators or standard breaker-failure protection, either fail to detect breaker-flashover conditions or operate too late to prevent extensive damage. As a result, breakers can explode, damaging neighboring equipment or placing substation personnel at risk. the sims 4 broken mods
