Preventing transformer failure is vital to the safe and reliable operation of any electrical network.

Transformer breakdowns usually cause power outages and interruptions. To compound the damage, unforeseen repair and maintenance costs are incurred, and new unexpected equipment is required.

Testing the condition and quality of transformer insulating oil provides data showing the actual condition of the transformer, and its remaining lifetime. Information from oil analysis can help anticipate potential failures, and guide precisely targeted maintenance and replacement plans. Transformer oil testing is a proven loss prevention technique that should be part of any condition based predictive maintenance program.
