Txoj kev daws teeb meem yooj yim ("Saib, Ncauj, Nug, Kov")
1. Saib xyuas (Saib qhov tshwm sim): Kev tshuaj xyuas qhov pom (kav, tawg, deformation, xeb, lossis hlawv cov cim ntawm lub casing); roj theem thiab xim (roj theem nyob rau hauv cov roj conservator, pob tshab rau me ntsis yellowish roj); kev mob ntawm cov khoom siv (nqus bushings, discolored hlau hlau pob qij txha, desiccant nyob rau hauv lub breather, txias system).
2. Tus ntxhiab tsw (Tshaj tawm tsw): tsw ntxhiab tsw ntxhiab tsw, uas feem ntau yog cov cim qhia ntawm coil aging, rwb thaiv tsev overheating, sib koom ua ke burnt- tawm, los yog sab hauv ib feem.
3. Nug (Trace Data): Tshawb xyuas cov ntaub ntawv khiav haujlwm, nug txog qhov hloov pauv hloov pauv, thiab sib piv cov ntaub ntawv ceeb toom nrog cov ntaub ntawv ua haujlwm.
4. Kov (kov, vibration, thiab ntsuas kub): ntsuas qhov kub thiab txias (yooj yim kov lub casing, bushings, thiab lead hlau pob qij txha nrog nraub qaum ntawm koj txhais tes); kev soj ntsuam kev co (suav nrog ntsuas ntsuas ntawm qis- zaus vibration yam ntxwv).
