Improvement of Relay Protection Trip Circuit
This paper presents a decision-based logic path that guides the reader from design constraints to the best-practice solution for their situation. Tziouvaras Abstract: The Relay Trip Circuit Design Working Group of the IEEE Power System Relaying Committee has prepared a Special Publication to document and share information about the practices of electric utilities in design of protective relay tripping circuits and associated apparatus. The protection relay tripping circuit refers to the critical electrical control loop that executes trip/close commands from protective relays to circuit breakers, ensuring rapid fault isolation in power systems. -
