description: Penelitian ini dilatar belakangi oleh adanya masalah blackout yang kerap timbul karena adanya kegagalan sistem proteksi tenaga listrik khususnya pada saluran transmisi di Indonesia. Penelitian ini bertujuan untuk mengetahui keandalan sistem proteksi melalui analisis koordinasi relai arus lebih yaitu Over Current Relay dan Ground Fault Relay pada trafo dengan tegangan 150/20 kV. Metode yang digunakan adalah metode kuantitatif dengan menentukan nilai arus setting dan nilai TMS menggunakan perhitungan manual sebagai variabel pembanding yang dianggap ideal. Untuk kemudian dibandingkan dengan arus setting dan nilai TMS yang ada di lapangan. Penelitian dilakukan di trafo 1 Gardu Induk New Kadipaten 150/20 kV 60 MVA. Berdasarkan pada penelitian yang dilakukan, ditemukan bahwa arus setting dan nilai TMS pada Over Current Relay sisi 150 kV dan 20 kV, serta Ground fault Relay sisi 150 kV dan 20 kV tergolong baik dan andal berdasarkan standar yang telah disepakati oleh pihak PLN. ;    This research is motivated by the existence of blackout problems that often arise due to the failure of the electrical power protection system, especially on transmission lines in Indonesia. This study aims to determine the reliability of the protection system through the analysis of overcurrent relay coordination, namely over current relay and ground fault relay on a transformer with a voltage of 150/20 kV. The method used is a quantitative method by determining the setting current value and TMS value using manual calculations as a comparative variable that is considered ideal. to then be compared with the setting current and TMS value in the field. The study was conducted at transformer 1, new kadipaten substation 150/20 kV 60 MVA. Based on the research conducted, it was found that the setting current and TMS value on the 150 kV and 20 kV side over current relays, as well as the 150 kV and 20 kV side ground fault relays are classified as good and reliable based on the standards agreed upon by the PLN.
