In electrical power system, protection system is required to operate reliably. Protection system ha a very important role to detect fault and to prevent the damage that caused by it. A good protection system will isolate the fault and prevent the other system which is not failing becomes failed. This will improve the reliability of the system and maintaining continuity of load supply. This will improve the reliability of the system and maintaining contuinity of load supply. This thesis aims to convey the protection study of large electric motor with case study of Forced Draft Fab (FDF) in Muara Karang Power Plant. From the result of study that value calculation TMS OCR = 2,5, it can already be said good based on chart that simulation on applicatiom ETAP 12.6.0.} }
