Oil Diagnostics and Analysis

  • 11 available

Course summary

A condition-based asset management approach can cut costs considerably by reducing unnecessary maintenance, identifying faults before they become failures and enhancing strategic planning for repairs and replacement. 

Oil sampling is one of the main techniques used to enable proper assessment of the condition of oil filled high voltage switchgear and transformers, enabling engineers to detect signs of deterioration that will lead to failure unless appropriate action is taken.

This course will give attendees a detailed understanding of oil analysis techniques by looking at the sampling and testing methodology and the analysis and interpretation of results. The course also provides an overview of handling, storage and disposal of insulating oil.

This one-day course can be taken as a standalone course or as an effective follow-on course to our two-day 'Transformers for Power Systems' course.
