reliablity

• (n-1)
• Process - management
• Automatic load reduction

13
maintenance

• Refinery plants turnarounds every 6 years-gt
  maintenance interval
• Solomon benchmarking-gt philosophy preventive
  maintenance Example
• Motors - high effort on inspection -gt
  reduction on maintenance costsinspection -
  vibration measurement - temperature monitoring
  bearing, stator- iron -gt closed motors revision
  cycle 12 years-gt open air ventilation 6
  year cycle
• Switch gears yearly thermography, stopp
  cleaning
• Circuit breakers - exchange of oil and wearing
  parts - according maintenance description of
  supplier

Resumee / Outlook

• Refinery on the growth-gt expected load 107MW
• Short circuit current
• Reshaping of grid-gt reliable long term
