To reduce the duration of blackouts for customers at PT. PLN (Persero) UP3 Kramat Jati Area, namely by applying the Automatic Change Over (ACO) cubicle. The purpose of this study is to determine the simulation of testing on Automatic Change Over (ACO) cubicles, reliability before and after application of Automatic Change Over (ACO) cubicles where this requires disturbance data before application of ACO cubicles and disturbances after application of ACO cubicles, and long duration. blackout. The method used to establish a reliability index. Average Interruption Duration Index (SAIDI) System Method, Average Interruption Frequency Index (SAIFI) System, Customer Average Interruption Duration Index (CAIDI) method. Calculation results at the E325 N substation before the application of ACO the SAIDI value of 333 minutes/customer/year SAIFI 6 times/year CAIDI 55.5 minutes/year and after the application of ACO the value of SAIDI 0.6 seconds/customer/year/ SAIFI 3 times/year CAIDI 0.2 seconds/year. At the E70 substation before the application of ACO the SAIDI value of 365 minutes/year/SAIFI customers 5 times/year CAIDI 73 minutes/year and after the application of ACO the SAIDI value of 0.6 seconds/customer/year SAIFI 3 times/year CAIDI 0.2 seconds/year . At the K155 N substation before the application of ACO the SAIDI value of 423 minutes/customer/year SAIFI 6 times/year CAIDI 70.5 minutes/year and after the application of ACO the SAIDI value of 0.6 seconds/customer/year SAIFI 3 times/year CAIDI 0.2 seconds/year.} }
