When an unexpected failure of a critical transformer occurs, the operational and economical impacts

on the utility are substantial. Today, many existing oil-insulated transformers used by electrical utilities

and other industries are approaching the end of their design life and are experiencing significantly

higher probabilities of failures.

Prognastics and Diagnostics

The prognostics and diagnostics software module on the Intellix MO150 is designed to provide

guidance whenever an alarm condition is present. It is intended to provide the first level of awareness

of what the alarm condition is all about, what the alarm condition means and what steps or actions

could be taken to improve the current situation.

The module will provide:

• Diagnostic: Identification of the alarm and/or set of alarm conditions.

• Prognostic: A set of statements that warn the operator about the  possible consequences for the

transformer if the situation is allowed to continue without any remedial action being taken.

• Recommendation: Summarizes the verifications that could be carried out, data that could be

collected to facilitate further actions and specific actions that could improve the current situation.
