Overcurrent backup protection for high-voltage switchgear relay protection
On high-voltage transmission, distance relays have the capability of serving both as primary protection and as remote backup protection. While the overcurrent relay (OCR) and the ground fault relay (GFR) function as a local backup in the event that the distance. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The selection and applications of. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A straightforward way of obtaining selective protection is to use time grading. Consideration is given to availability and location of breakers, current sensing devices, and disconnect switches, as well as bus-switching scenarios, and their impact on the selection and application of bus protection. Graduated with a Master of Science in Electrical Engineering from The University of Texas at Dallas in 2018 and with a Bachelor of.
