Penelitian ini bertujuan untuk menguji efektivitas metode Grounding RAISSA (Rangkaian eStafet di laS
dengan pipA) dalam menurunkan resistansi pentanahan dan mengurangi gangguan transformator distribusi
akibat sambaran petir. Metode penelitian menggunakan pendekatan eksperimental lapangan dengan
desain one-group pretest-posttest pada lima gardu distribusi 20 kV di Penyulang Pluto, ULP Pendopo, yang
dipilih secara purposif berdasarkan nilai resistansi awal >10 Ω dan wilayah rawan petir. Implementasi
metode RAISSA dilakukan melalui penanaman elektroda pipa galvanis diameter 1 inci yang disambung
secara estafet menggunakan teknik pengelasan listrik. Hasil penelitian menunjukkan bahwa metode
RAISSA berhasil menurunkan resistansi pentanahan dari rata-rata 30,53 Ω menjadi 3,12 Ω atau turun
sebesar 86,4%, dengan seluruh gardu mencapai nilai di bawah 5 Ω sesuai standar PUIL 2020. Penurunan
tertinggi terjadi pada Gardu L10004 dari 79,27 Ω menjadi 3,51 Ω (95,6%). Hasil implementasi bahkan
melampaui prediksi teoritis karena kualitas sambungan las yang menjamin kontinuitas elektris optimal.
Keberhasilan ini berimplikasi pada peningkatan keandalan sistem proteksi petir, mengingat sambaran petir
merupakan penyebab dominan gangguan (37,5%) di wilayah studi. Metode Grounding RAISSA terbukti
efektif, ekonomis, dan dapat direkomendasikan sebagai solusi perbaikan pentanahan pada gardu distribusi
di wilayah tanah berresistivitas tinggi dan rawan petir.
