In the Shoes of Field Engineers | Onsite Power Transformer Commissioning

Best practices for testing power transformers during onsite commissioning from our field experts.

In the shoes of field engineers – This is one of many Energy Talks episodes in which we offer you practical tips for testing electrical equipment at power substations.

During the onsite commissioning of power transformers, a set of tests are performed to confirm that the power transformer can be put into service.

In this episode of Energy Talks, OMICRON field testing experts Bernhard Engstler  and Marcus Stenner talk about their practical experience with the onsite commissioning of power transformers.

Bernhard and Marcus recommend which tests should be performed on power transformers to check a variety of parameters during commissioning. They also describe how the test results are evaluated and reported.

Bernhard and Marcus also offer best practice tips, including how the use of multi-functional testing devices and following a defined testing workflow improve efficiency as well as ensure safety and reliable measurement results.

Lastly, they describe the available OMICRON testing solutions for both onsite commissioning and troubleshooting throughout the service life of power transformers.

Power Transformer Testing


“Fingerprint measurements should be the goal during commissioning, which are compared with future measurements – it is the easiest way to detect problems and deviations from when the transformer was known to be in good condition.

- Bernhard Engstler, Field Testing Expert, OMICRON

“During the commissioning of power transformers, there are a lot of things that can impact safety and efficiency onsite – that is why I like to have a prepared and automated test plan.

- Marcus Stenner, Field Testing Expert, OMICRON
