ABSTRACT
The protection system identifies the disturbance that occurs and separates
the affected part of the disorder from other parts that are working normally. The
main protection equipment of the power transformer is a differential relay that
works with the current balance method that is in accordance with the law of
kirchoff current that is, the current that goes equal to the current leaving the
branch point. Differential relays must work selectively that is must be able to
distinguish interference located in its main security area and work quickly. Relays
must not work at all because of interference outside the security area or there is
absolutely no disturbance. The method used in this study is the retrieval of
secondary data at Garuda Sakti Substation and calculating manual settings. From
the results of calculations on transformer 1 obtained CT ratio 1 300:1 and CT
ratio 2 2000:1, error mismatch 0.916% and 1.023%, secondary current CT side
150 kV 0.769 A and side 22 kV 0.787 A. For differential current obtained 0.018 A,
restrain current 0.778 A, slope1 2.31%, slope2 4.63%. In transformer 3 obtained
CT ratio 1 300:1 and CT ratio 2 2000:1, mismatch error 0.88% and 1.125%,
secondary current CT side 150 kV 0.769 A and side 22 kV 0.886 A. For
differential current obtained 0.097 A, restrain current 0.817 A, slope1 11.87%,
slope2 23.74%. To find out the performance of differential relay work on the
power transformer, modeling and simulation are done with ETAP 16.0 software.
