which generation does your equipment belong to?

Recommendation of preventive maintenance

after years of operation, an oil-immersed transformer reaches its end of life. the failure rate of oil-immersed transformers tend to become high after 15 years of operation. even though the appearance is fairly good, there are possibilities of dangerous conditions.  

Benefits of preventive maintenance

  • Preventive Maintenance means “preventive action against failure occurrence” and is abbreviated as PM.
    It is a particularly important type of maintenance.
  • This “preventive maintenance” exerts its power effectively during the “wear-out failure period” in the bathtub curve.

What you can expect from PM:
– Accident prevention – Prevention of aging degradation – Extension of life span
