3 Condition Assessment (PMT & PMS)

4 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

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

Electrical Current Carrying (SS1) W E I G H T N F A C O R X Electrical Switching (SS2) X Electrical Insulation (SS3) X Hasil Inspeksi Level 1 X Indeks Kondisi PMT Driving Mechanism (SS4) X Control System (SS5) X Hasil Inspeksi level 2 X Mechanical Structure (SS6) X Grounding (SS7) X Dilakukan adjustment berdasarkan nilai criticality masing-masing failure mode (FMECA), sense of engineering

7 Perhitungan Indeks Kondisi PMT
PMT 500 kV = (0.04 x SS1)+(0.3 x SS2)+(0.33 x SS3)+(0.11 x SS4) +(0.19 x SS5)+(0.02 x SS6)+(0.01 x SS7) PMT 150 kV = (0.06 x SS1)+(0.16 x SS2)+(0.26 x SS3)+(0.20 x SS4) +(0.29 x SS5)+(0.02 x SS6)+(0.01 x SS7) PMT 70 kV = (0.07 x SS1)+(0.21 x SS2)+(0.29 x SS3)+(0.15 x SS4) +(0.25 x SS5)+(0.02 x SS6)+(0.01 x SS7) PMT 20 kV = (0.05 x SS1)+(0.15 x SS2)+(0.51 x SS3)+(0.11 x SS4) +(0.15 x SS5)+(0.02 x SS6)+(0.01 x SS7) Kategori : Baik = 7.5 – 9 Sedang = 5.5 – 7.49 Buruk = 0 – 5.49 detail
