Transformer oils are subject to electrical and mechanical stresses while a transformer or other electrical distribution equipment is in operation. The analysis of insulating oils provides information about the oil, but also enables the detection of other possible problems, including contact arcing, aging insulating paper and other latent faults and is an indispensable part of a cost-efficient electrical maintenance program.

Though the failure risk of a transformer and other oil-filled electrical equipment is small, when failures occur, they inevitably lead to high repair costs, long downtime and possible safety risks. By accurately monitoring the condition of the oil, suddenly occurring faults can be discovered in time and outages can potentially be avoided.

Some specific parameters of transformer or insulating oil should be considered to determine the serviceability of that oil.
