Abstract :
The DC system has an important role in the operation of equipment at the substation. In the 150 kV substation, the dc installation system is used as a DC voltage reserve supply for protection relays, triping coil / closing coil for emergency lighting / alarm, namely the 110 vdc system. The battery is one of the main components in the substation. If under normal circumstances the DC system is supplied directly by the rectifier. If there is an emergency/abnormal situation such as a blackout (loss of voltage) caused by a disturbance in the rectifier / transformer selfuse, the battery will directly supply the load for a certain period of time. In order for the battery to be used in good condition,maintenance is needed such as keeping the battery room clean and carrying out battery testing using the BCT (Battery Capacity Test) method. Battery condition can affect battery performance if a blackout occurs. From the results after testing the batteries used in GIS Kebon sirih, it was found that the battery capacity used in the first unit was 209.1 Ah and the second unit was 209.7 Ah. and efficiency of 98.6% and 98.9%. And the electrolytes in each cell are in good condition.
