		abstract={The operation of a complex electric power system cannot be separated from the reliability of each component in it, especially the equipment at the substation. Before the operation of the equipment at the substation. The frequent occurrence of abnormal conditions in the system, one of which is caused by internal disturbances, therefore it is necessary to take preventive actions to anticipate them, namely by conducting individual testing on each equipment at the substation then commissioning is carried out. The method used is a quantitative method by collecting test data and then analyzing the data. Visual inspection results of all equipment in good condition. Circuit Breaker test results insulating power more than 500 M?, Minimum Pick Up 60-64 v (Close), 54-74 v (trip 1), 56-70 v (trip 2), contact resistance 65.14-67.67 ?? , operating time 56.80 -59.20 ms (Closed), 18.50-18.90 ms (travel), 41.00-47.10 ms (combination of both). Insulation resistance of the disconnecting more than 100 G?, contact resistance 57.6-59.62 ??. Surge counter LA counter numbers increase. For transformers, the winding current is not less than 1% of the rating, the polarity (+) and (-) are still appropriate, and the winding resistance is still in accordance with the ratio of voltage, current and resistance, the insulation with the smallest value is 9,77 G? and the largest is 456 G?. From the results of commissioning all equipment that has passed commissioning is ready to be operated and those that have not passed commissioning must be repaired.}
