Electronic Over Current Relays Shop Now Eezee 3. common overcurrent protection schemes include time graded systems using definite time relays, current graded systems using instantaneous relays, and combinations of both for selective coordination on radial distribution feeders. download as a pptx, pdf or view online for free. The document then discusses over current relay types including instantaneous, definite time, and inverse time relays. it provides examples of how over current relays are applied and coordinated on feeders and defines ratings for proper over current device selection.
Protection System Lecture 21 Relays Pptx These relays can replace the following ge electromechanical & static relay types that require a time overcurrent range of 0.5 15.9 amps and an instantaneous overcurrent range of 1 159 amps: iac51 iac53 iac55 iac57 iac66 iac77 iac95 ifc51 ifc53 ifc57 ifc66 ifc77 ifc95 sfc151 sfc153 sfc177.
