Focus: operating principle, arcing, exhaust, and applications in medium-voltage distribution protection In medium-voltage distribution systems, fuses are used to interrupt fault current and protect equipment such as transformers, feeders, cables, and capacitor banks. Two concepts that are often compared are expulsion fuses and current-limiting fuses. Both generate an arc during
In oil & gas operations, electrical power is more than just a utility—it is the backbone of production. At Pertamina Hulu Rokan (PHR), particularly in Rokan Working Area Zone 2 & 3, maintaining a stable and reliable power system is essential to ensure uninterrupted operations.Recognizing this critical need, PT Jashen

Dari kecil kita diajarin satu hal sederhana: listrik gak boleh kena air.Dan itu benar. Di kebanyakan fasilitas industri, sedikit genangan saja sudah cukup bikin panel mati, sistem drop, dan operasional berhenti. Tapi menariknya, masalahnya sering bukan di banjirnya.Masalahnya ada di sistem yang memang tidak didesain untuk menghadapi kondisi ekstrem.Switchgear konvensional
Di banyak fasilitas, sistem listrik masih mengandalkan proteksi konvensional yang membutuhkan waktu menit untuk mendeteksi dan mengisolasi gangguan. Bukan karena operator lambat—tetapi karena arsitektur kontrol lama memang tidak dirancang untuk merespons secara instan. Akibatnya, fault kecil bisa berkembang menjadi outage besar, memengaruhi operasional dan layanan pelanggan. Solusinya? Distributed Intelligence dari Vista Switchgear. Teknologi
Di banyak fasilitas, operator masih bekerja dekat switchgear yang punya risiko ledakan akibat tekanan internal dan arc flash. Bukan karena kurang hati-hati—tetapi karena desain konvensional memang menggunakan ruang udara terbuka yang rentan terhadap fault. Solusinya? Vista Compact Welded-Steel Tank. Sistem 100% tertutup yang memberikan perlindungan menyeluruh untuk personel dan aset
