1. A method for monitoring primary devices of a power system via diagnostic devices, the method comprising:

  • in a first diagnostic device;

    collecting operational diagnostic data from a first primary device, and determining health indicator data for the first primary device from readings of a sensor, or from a result of a remote query, or from manual inspection, or from regular services performed by a human on the first primary device;

    identifying diagnostic correlation data from the health indicator data and from correlated operational diagnostic data of the first primary device, which correlated operational diagnostic data is linked with the health indicator data;

    adapting a diagnostic rule to the identified diagnostic correlation data, wherein an original diagnostic rule is modified by calculating a change in a diagnostic identifier associated with operational data of the first primary device and is applicable to operational diagnostic data for generating a diagnostic warning indicative of a health state of the primary device;

    communicating the adapted diagnostic rule to a second diagnostic device; and

    in the second diagnostic device;

    generating a diagnostic warning of a second primary device by applying the adapted diagnostic rule of the first diagnostic device to operational diagnostic data collected from the second primary device.
