Determine Transformer Health Using Oil Characteristics

Home / Services /Insulating Oil Testing

Routine oil analysis is a key to successful maintenance program.
Regular oil testing provides information essential to determining the condition of your equipment.

We work with clients to create cost-effective test packages applicable to their particular equipment and mechanical designs. Companies typically spend at least 10% of their revenues on maintenance and equipment repair. Add to this the cost of equipment downtime, decreased productivity, and devalued used machines, and this can easily add up to Millions of rupees per year. Standard testing programs for equipment reliability are comprised of routine tests that can meet most service requirements.

Our basic preventative maintenance package is designed to provide early detection of:

  • Problems in the initial stages of development
  • Excessive wear and the source of that component’s wear
  • Unwanted contaminants such as dirt, water, coolant, nitration and incorrect oil 
  • The lubricant’s suitability for further service time, i.e. oil and equipment degradation
  • Filtration or regeneration if needed
  • Dilution of lubricants
  • Misapplication of lubricants
  • The oil’s physical, chemical and dielectric properties

Companies that take oil analysis to the next level concentrate on root cause analysis. Equipment diagnosis and evaluating test results consists of looking at both the health of the equipment and the integrity of the oil. Trending of the test data over a period of time is a valuable tool to monitor ongoing equipment condition and allows you to predict corrective action before interruption to operations or increased maintenance costs occur.

Effective trending analysis will minimize equipment downtime, permit more efficient maintenance scheduling, protect warranty claims, and increase equipment resale value.
