Abstract :Protection coordination is the heart of all power systems. To insure a quality and reliable operation of the power systems, an electrical fault must be cleared within short time. This can be achieved by proper coordination between the protection relays. In Siddik Kardesler Substation the MV voltage feeders’ protection is provided by overcurrent relays. This paper is principally concerned with practical protection coordination of the electrical substation by using substation as case study. In the Part-2, distance and differential protection will be discussed. Finally, after test and commissioning, the substation is successfully energized without problem.
