Once a transformer failure happens, money is gone!

There is a huge pressure on everybody to repair (or substitute) the transformer as quickly as possible to get back in service. Damaged parts are scrapped and there is a rush to manufacture new ones.

However, there is no safe and reliable repair without understanding all the reasons for the transformer failure (many people stop at the first one they found). Without this, additional failures may occur and then there may not be any spare transformer left.

Whether you are a transformer user or a manufacturer, you cannot afford to miss the opportunity to learn why a transformer failed (internal problems due to design, quality, etc.) so that service can be restored in a safe and reliable way.

Unfortunately, emotions tend to run high in these situations and people may be more interested in assigning blame instead of preventing new transformer failures (one of Murphy's laws states "a man who smiles when things go wrong knows who to blame", but probably does not know how to get the transformer back in service).

Jobs are often at risk and it may be difficult to investigate the matter in a detached and rational way or, simply, there is no skilled manpower to dedicate to the investigation.

You can count on our transformer consultants's skills, independence, and respect for confidentiality to systematically investigate and discover the roots of the failure and prevent new ones.

The more information we have for the investigation, the higher our chance of success. So when a failure happens:

  • Call us as soon as possible
  • Do not scrap any part of the transformer
  • Gather as much information as possible about the transformer failure (protection recording, photos, etc.)
  • Get a copy of the transformer's factory acceptance tests and, if possible, design data.
  • Gather any results of transformer tests on site (commissioning, DGAs, etc.)
