Summary of Revision, IEEE C37.119‐2016, Guide for Breaker Failure Protection of Power Circuit Breakers
This summary paper covers principles of breaker failure protection and changes and additions that comprise IEEE C37.119-2016, Guide for Breaker Failure Protection of Power Circuit Breakers. The scope is expanded to include breaker failure protection of generator unit breakers. In addition to breaker failure initiation from fault conditions, initiation from automatic or manual tripping and closing devices that detect potentially damaging non-fault conditions is included. Column ground fault protection, breaker differential protection, and tandem breaker protection schemes are added. Different utility philosophies about how to apply breaker failure protection including ways to avoid single points of failure are discussed.
