Condition assessment & diagnostics

Condition assessment

After several years of operation, it is important to evaluate the condition of the transformer to determine options to extend the life of the asset or to minimize the probability of a future problem. Prolec GE has the knowledge, experience, design information, and trained personnel capable of performing such studies. If needed, Prolec GE can incorporate analysis of networks, power systems, and transient events that may impact the integrity of the specific transformer application.

Prolec GE has a combination of factory and field experts at its Monterrey facility and in other countries. Our evaluation is a complete study performing a diagnosis of key elements of the transformer and its application. This evaluation typically results in an estimate of the remaining productive life and the recommended maintenance or other actions relative to improving the reliability or increasing the useful life of the transformer.


Failure investigation

In the event a transformer fails during operation, the two most important tasks that need to be performed are:

  1. Locate and install a replacement as soon as possible.
  2. Perform a complete failure analysis to determine the root cause of the problem.

For distribution transformers (industrial, commercial, residential), Prolec GE has developed a set of tests (electrical and oil analysis) which can be performed at the site and which are used to assess abnormalities and define an action plan for the transformer repair or replacement.
