Electric power protection can prevent damage to the equipment is interrupted, and equipment that are crossed by fault currents but it also can reduce or isolate the affected part of the system as small as possible and as quickly as possible to prevent the spread of disturbance. In these discussions, namely to optimize the work of the protection system installed on the feeder Juwita in substations Angke in UP3 Bandengan. To optimize the work of the protection system installed on the feeder needs to be coordination between rele installed from downstream to upstream. Rele coordination of calculation obtained the following results which Time delay (Td) is 0,4 second for Circuit Breaker Outgoing Middle Point (CBOMP) and Time delay (Td) is 0,7 second to Circuit Breaker Outgoing substations.} }
