The laboratory project is divided in three parts: I) Establish a test bench for relay setting and testing, including use of high speed data from the local process bus for transformer and bus differential, over-current, and distance protection; II) Establish a SCADA interface. A Power System Protection lab will be established in this project to meet the needs from each of the 4 PhD students and to demonstrate the developed technology. The laboratory will consist of modern over-current, directional over-current, distance and differential relays. In this video, Ellen Bachman, District Application Engineer, explains how protective relays function as the "brains" for medium voltage breakers, ensuring faults are isolated quickly to prevent equipment damage and maintain system reliability. Power System Protective Relays: Principles & Practices Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 1 Power System Protective Relays: Principles & Practices Presenter: Rasheek Rifaat, P. Eng, IEEE Life Fellow IEEE/IAS/I&CPSD Protection & Coordination WG Chair Jacobs Canada.
