RDK three-phase electronic sectionalizer: 12-40.5kV, 200-315A, lightning impulse 75-220kV, 1-4s short-time 10kA, making peak 16-25kA. For overhead-line fault isolation with upstream reclosers.
RDK pole‑mounted three‑phase electronic sectionalizer adopts CT energy‑harvesting without external auxiliary supply, distinguishes temporary / permanent faults by counting upstream trips, with visible open gap, manual closing by insulated stick and maintenance‑free. It meets relevant IEC/ANSI sectionalizer standards with configurable pickup‑current & counting‑times.
Three-phase electronic pole mounted sectionaliser for 12kV 40.5kV systems, enabling fast fault isolation and enhanced overhead grid reliability.
Pole-mounted vacuum automatic sectionalizer for 12kV and 24kV lines, enabling smart fault isolation to improve grid reliability.
Rockwill voltage-time type intelligent sectionalizer complete set for 12kV distribution automation. Fault isolation, power restoration, remote monitoring via GPRS/fiber.
Tidak diperlukan sumber daya bantu eksternal. Perangkat ini mengambil energi dari transformator arus bawaan, serta menyelesaikan logika deteksi arus gangguan dan penghitungan melalui mikrokontroler internal.
Setelah gangguan permanen diatasi, operator dapat menutupnya secara manual menggunakan tongkat operasi berisolasi. Penggantian suku cadang tidak diperlukan. Alat akan mereset secara otomatis jika gangguan bersifat sementara dan tidak mencapai ambang batas penghitungan.
Tiga kondisi harus dipenuhi secara bersamaan: arus gangguan melebihi setelan pickup; jumlah hitungan yang telah ditetapkan (1-4 kali) tercapai; saluran kehilangan tegangan dan arus sisa di bawah 300 mA.
