How Often Should I Pull Transformer Oil Samples?

A common question we get from our customers is “How often should I pull transformer oil samples?”

Our training manager Mark Stone has the answer in our latest video:

Most of the industry finds that insurance companies set minimum requirements for their transformer oil testing. In most cases, annual oil samples will be required, and that is what Southwest Electric Co recommends as a minimum. But, an oil sample schedule isn’t a one-size-fits-all plan. For example, more expensive transformers or transformers with greater criticality in your facility might require quarterly testing in addition to an annual oil test. Contact Southwest Electric Co. with your questions – we can create and implement the maintenance plan that is perfect for your facility.
