ANALISIS KINERJA RELAI DIFERENSIAL PADA GENERATOR PLTA PANGLIMA BESAR SOEDIRMAN MRICA BERDASARKAN DATA PENGUJIAN LAPANGAN
Abstract
Keandalan system proteksi generator sangat bergantung pada kinerja Relai diferensial yang harus mampu mendeteksi gangguan internal secara cepat dan selektif. Kinerja Relai dapat menurun akibat penuaan peralatan, perubahan konfigurasi sistem, dan ketidaksesuaian pengaturan, sehingga pengujian berkala berbasis data lapangan menjadi sangat penting. Penelitian ini mengevaluasi kinerja Relai diferensial tipe ASEA RADSB melalui pengujian arus setting, waktu operasi, karakteristik restraint, dan second harmonic restraint. Hasil pengujian menunjukan arus pickup rata-rata sebesar 326,889 mA berada dalam rentang standar pabrikan 315-385 mA, waktu operasi rata-rata 30,667 ms sesuai standar 27-33 ms, karakteristik restraint berada dalam batas aman pada injeksi arus 1,5 A dan 3 A, serta persentase harmonisa kedua sebesar 14,79% masih dalam rentang 14-18%. Berdasarkan hasil tersebut Relai diferensial ASEA RADSB dinyatakan beroperasi normal dan layak digunakan sebagai system proteksi generator.
