Abstract :
In the interbus transformer (IBT) protection system, it is the main element in the distribution system where power distribution can be disrupted and obstructed and even damage to equipment. To maintain the N-1 criteria and setting the overload shedding (OLS) to work at 110%, the load on the Interbus Transformer (IBT) cannot exceed 60% to maintain system reliability. Disturbances that often occur in Interbus Transformer (IBT) are excessive loads as a result of one of them, namely criteria N-1 or excessive consumer power, so this can be overcome by applying overload shedding. Overloading is a scheme to mitigate overcurrent in transmission equipment or transformers by removing the load in other locations so that widespread blackouts do not occur. Evaluation of the application of overloading the interbus transformer (IBT) Balaraja Baru 1.2 ? Lengkong 1.2, namely calculating the setting current and then the load shedding target so that it can be known when OLS installation and when there is no OLS installation in the distribution system.
