    摘要： The present invention provides a method, the corresponding software implementation of the method, and an apparatus for monitoring primary devices of a power system. The method comprises the steps of: collecting operational diagnostic data (26) from a first primary device (16a); identifying a change of a diagnostic indicator (35) based on the operational diagnostic data (26); adapting a diagnostic rule (28) to the identified change, wherein the diagnostic rule (28) is applicable to the diagnostic data for determining a diagnostic warning (21) which indicates a diagnostic state of a primary device (16a, 16b); and providing a diagnostic warning (21) of a second primary device (16b) by applying the adapted diagnostic rule (28) to operational diagnostic data (26) collected for the second primary device (16b).
