Condition Assessment (PMT & PMS)

Alur Desain asesmen kondisi PMT & PMS W E I G H T N F A C O R W E I G H T N F A C O R Critical failure mode SS1 FMEA FMECA Inspeksi Level-1 SS2 SS3 Inspeksi Level-2 Indeks Kondisi 1,6,9 SS4 SS5 SS6 SS7 Asesmen Kondisi Adjustment weight Sense of engineering

FMECA Critical failure mode - PMT 500 kV Risk = Effect x Probability detail Probability = frequency ; Effect = Safety + System + Environment + Cost
