Transformer Maintenance: The Cheapest Form of Insurance

Statistics show that 73% of transformer failures are caused by insulation failure and that 58% of failures are preventable. What are the causes of electrical transformer insulation breakdown?

This Electricity Today article provides an overview of the causes of insulation breakdown in electrical transformers. With the causes identified, preventive maintenance can be used to reduce the number of transformer failures.

The article concludes by reiterating the importance of transformer maintenance:

"Start the planning stage by identifying the most important transformers in your system. These will be easy to find since they are the ones that if lost, will cause the greatest effect on your plant or production process."

"Once you have a list of the important transformers defined, then determine" [which has the highest risk of failure]. "A strong maintenance program should reduce the effects of the risk factors or provide you with a way of monitoring their effects."
