Electromechanical Differential Relays Misoperation and Investigation. Part 2
In January 2022, an industrial site had a partial blackout due to an improper operation of one of its main electromechanical differential relays. The system was being upgraded and reconfigured, and a mistake was introduced during the demolition process. This paper describes the investigation into the nuisance trip and how careful demolition could have prevented this issue.
