    Abstract

    Pemutus tenaga (PMT) merupakan komponen penting dalam sistem distribusi tenaga listrik karena berfungsi sebagai perangkat proteksi saat terjadi gangguan. Salah satu bagian utama dalam PMT adalah tripping coil, yaitu kumparan elektromagnetik yang berperan dalam memutuskan arus secara otomatis. Permasalahan utama dalam penelitian ini adalah untuk menganalisis kemampuan kerja tripping coil pada PMT 20 kV di gardu induk Cigareleng, guna memastikan apakah coil masih mampu bekerja optimal dalam kondisi tegangan suplai yang bervariasi, serta mengidentifikasi faktor-faktor yang memengaruhi performanya. Penelitian ini dilatarbelakangi oleh kebutuhan akan sistem proteksi yang andal dalam jaringan distribusi, serta pentingnya pemeliharaan preventif terhadap komponen internal PMT yang jarang dikaji secara mendalam. Metode yang digunakan adalah field research (penelitian lapangan), dengan pengumpulan data dilakukan melalui pengukuran langsung nilai tegangan, arus, dan resistansi tripping coil, serta pengujian batas tegangan minimum operasional coil yang dilaksanakan dari tahun 2023 hingga 2025.Hasil penelitian menunjukkan bahwa tripping coil masih berfungsi dengan baik pada tegangan 110 – 112 V, namun mulai menunjukkan pelemahan kinerja di bawah 77 V, dan tidak bekerja efektif di bawah 50,8 V. Kebaruan penelitian ini terletak pada pendekatan pengujian batas tegangan minimum operasional tripping coil secara langsung di lapangan pada sistem distribusi 20 kV, yang memberikan informasi krusial mengenai ambang batas kerja aktual komponen dalam kondisi suplai tidak ideal, serta menyajikan rekomendasi preventif yang aplikatif untuk strategi pemeliharaan berbasis kondisi. Temuan ini menjadi dasar penting bagi evaluasi kinerja sistem proteksi serta pengambilan keputusan dalam strategi pemeliharaan berbasis kondisi aktual. Circuit breakers (PMT) are an important component in the electric power distribution system because they function as a protection device when a disturbance occurs. One of the main parts of the PMT is the tripping coil, which is an electromagnetic coil that plays a role in automatically disconnecting the current. The main problem in this study is to analyze the working capability of the tripping coil on the 20 kV PMT at the Cigareleng substation, to ensure whether the coil is still able to work optimally under varying supply voltage conditions, and to identify factors that affect its performance. This research is motivated by the need for a reliable protection system in the distribution network, as well as the importance of preventive maintenance of the internal components of the PMT which are rarely studied in depth. The method used is field research, with data collection carried out through direct measurements of the voltage, current, and resistance of the tripping coil, as well as testing the minimum operational voltage limits of the coil carried out from 2023 to 2025. The results of the study show that the tripping coil still functions well at a voltage of 110 – 112 V, but begins to show performance weakening below 77 V, and does not work effectively below 50.8 V. The novelty of this study lies in the approach of testing the minimum operational voltage limits of the tripping coil directly in the field on a 20 kV distribution system, which provides crucial information regarding the actual working threshold of components under non-ideal supply conditions, as well as presents applicable preventive recommendations for condition-based maintenance strategies. These findings provide an important basis for evaluating the performance of protection systems and decision-making in actual condition-based maintenance strategies.
