Abstract :
The common protection that used in medium voltage systems is circuit breaker which is works ruled by over current relay. Between over current relay in incoming 20 kV and over current relay in outgoing 20 kV must have good coordination. Ungood coordination of over current relay can cause a security overlap in the incoming 20 kV and in the outgoing 20 kV and can cause blackout in feeder. This final project is discusses about evaluation of coordination between incoming side of over current relay 20 kV with over current relay 20 kV outgoing side on Siluang feeder in Metro?s substation, by comparing the existing data in the field with calculation result data. From the calculation result of TMS over current relay on the incoming side 20 kV is 0.259 and TMS in the outgoing side of 20 kV is 0.192 with a short circuit current 3 phase is 11275.649 Ampere, the current 2 phase short circuit is 9762.991 Ampere, and 1 phase short circuit current is 72.151 Ampere.
