  1. A Study of … GIS ASSESSMENT By Tim RJBR

  2. GIS di RJBR • GIS GITET Saguling • Merk : Mitshubishi/Alsthom • Sistem 500 kV • Outdoor • GIS Kiaracondong • Merk : Alsthom • Sistem 150 kV • Indoor • GIS Cibabat • Merk : Alsthom • Sistem 150 kV • Indoor

  3. GIS Cibabat

  4. Failure Path untuk assessment GIS Fungsi Current Carrying Partial Discharge Fungsi Switching Fungsi Insulasi Losses Transfer Daya Terbentuknya partikel bebas Perubahan Fisik Konduktor Kegagalan driving mechanism Kelembaban SF6 tinggi Korosif Kontak/ Konduktor Adanya Uap Air (H2O) Decomposition products (gas & powder form) Kegagalan fungsi rele bantu Timbulnya Kadar Asam (HF) Adanya Kebocoran (gas leakage) Arcing

  18. Penutup • Pengujian yang telah dilaksanakan meliputi: • a. Pengujian Fungsi Insulasi: • i. Pengukuran Purity • ii. Pengukuran dewpoint • iii. Pengukuran decomposition product • iv. Pengukuran Parial Discharge • b. Pengujian Switching • Pengujian dengan menggunakan breaker analyser • Penggantian SF6 merupakan tindakan yang telah dilaksanakan untuk perbaikan kondisi insulasi • Hasil uji fungsi insulasi di atas, perlu dilakukan analisis lebih lanjut dengan komparasi terhadap hasil uji seperti Partial Discharge
