Sun Wei-ben · Power System Technology · 2003
The key issue of condition maintenance is how to work out a reasonable maintenance schedule based on the evaluation of the condition of electric power equipments. A graded approach to evaluate the condition of electric power equipments is proposed by means of grading and weighting of their condition information and a usable quantitized equipment condition evaluation system is established. Some basic principles relevant to the drafting of the Guide for Condition Maintenance of Electric Power Equipment are dissected and necessary arguments are performed. Three principles are emphasized on, i.e. analysis of equipments condition should be based on experiment (including on-line monitoring) and family quality fault events and itself quality events; hundred grade system used to evaluate equipments condition and experiment item should be introduced and employed; the necessity of digital administration should be considered at the beginning of mapping out the Guide.
