Abstract

For monitoring diagnostic rules of a power system, an exemplary method is disclosed and includes collecting operational diagnostic data from a first primary device; identifying a change of a diagnostic indicator based on the operational diagnostic data; adapting a diagnostic rule to the identified change, wherein the diagnostic rule is applicable to the diagnostic data for determining a diagnostic warning which indicates a diagnostic state of a primary device; and providing a diagnostic warning of a second primary device by applying the adapted diagnostic rule to operational diagnostic data collected for the second primary device.
