Abstract :
Feeder failure can cause damage to the transformer. As a result of this short circuit interference which causes dynamic / mechanical force so that it can damage the transformer winding. Coordination of outgoing and incoming OCR / GFR settings needs to be done. The benefit of resetting OCR / GFR feeder and incoming 20 kV is that the new protection coordination setting will further shorten the duration of the disturbance so that the time or transformer can be longer according to the standard. The results of the calculation of withstand capacity for Transformer 4 at the GI Bogor Baru Substation according to the collective agreement show the ISQT value compared to K which decreased from 2.3 to 0.8 which was obtained from the 2016 collective agreement. Analysis of the calculation of withstand capacity with a setting value of Ihs2 = 2.75 x In the transformer parameters are within safe parameters.
