Abstract

A system (30) includes an analysis engine (34) and a notification engine (38) for selective notification of a condition (72) of an apparatus (26) monitored by a monitoring device (28). A method executed by the system (30) receives (116) data elements (58) from the monitoring device (28), processes (118) the data elements (58) to detect the condition (72) of the apparatus (26), and determines that the condition (72) defines an exception (74) to a normal condition (70) of the apparatus (26). A first notice (60) of the condition (72) is conveyed (146) to a responsible party (59) at a first instance of determination of the exception (74), and conveyance of a second notice (60) is prevented (140) at a second, subsequent, instance of determination of the exception (74). In addition, communication of the normal condition (70) of the apparatus (26) is prevented.

Claims

1. A method for selective notification of a condition of an apparatus monitored by a monitoring device comprising:

receiving data elements from said monitoring device;

processing said data elements to detect said condition of said apparatus;

determining that said condition defines an exception to a normal condition of said apparatus;

conveying a first notice of said condition to a responsible party at a first instance of determination of said exception; and

preventing conveyance of a second notice at a second instance of determination of said exception, said second instance occurring subsequent to said first instance.

2. A method as claimed in claim 1 further comprising:

ascertaining that said condition is said normal condition of said apparatus; and

preventing communication of said normal condition to said responsible party.

3. A method as claimed in claim 1 further comprising:

associating discrete responsible parties with a plurality of fault conditions possible at said apparatus; and

determining from said exception one of said fault conditions such that said conveying operation selects said responsible party associated with said one fault condition from said discrete responsible parties.

4. A method as claimed in claim 3 wherein said determining operation includes identifying a fault type of said one fault condition such that said conveying operation selects said responsible party associated with said fault type.

5. A method as claimed in claim 3 wherein said determining operation includes identifying a fault location of said one fault condition such that said conveying operation selects said responsible party associated with said fault location.

6. A method as claimed in claim 1 further comprising:

associating discrete responsible parties with severity levels for a fault condition possible at said apparatus; and

determining from said exception one of said severity levels such that said conveying operation selects said responsible party associated with said one severity level from said discrete responsible parties.

7. A method as claimed in claim 1 wherein said data elements are first data elements, said exception is a first exception, and said method further comprises:

receiving second data elements from said monitoring device;

processing said second data elements to detect a second condition of said apparatus;

determining that said second condition is a second exception that differs from said first exception; and

transferring a third notice of said second condition upon determination of said second exception.

8. A method as claimed in claim 7 said transferring operation transfers said third notice to a second responsible party associated with a fault condition possible at said apparatus, said fault condition being defined by said second exception.

9. A method as claimed in claim 7 wherein said first exception defines a first severity level of a fault condition possible at said apparatus, said second exception defines a second severity level of said fault condition, and said transferring operation transfers said third notice to a second responsible party associated with said second severity level.

10. A method as claimed in claim 9 further comprising:

determining that said second severity level indicates a greater seriousness of said fault condition than said first severity level; and

identifying said second responsible party as having greater authority than said responsible party in a predetermined chain of authority.

11. A method as claimed in claim 7 wherein said first exception defines a first severity level of a fault condition possible at said apparatus, said second exception defines a second severity level of said fault condition, and said method further comprises:

determining that said second severity level indicates a lesser seriousness of said fault condition than said first severity level; and

delaying said transferring operation until said fault condition is detected at said second severity level for a predefined duration.

12. A method as claimed in claim 1 further comprising:

receiving an acknowledgement of receipt of said first notice from said responsible party; and

recording said acknowledgement in an acknowledgement database.

13. A method as claimed in claim 1 further comprising:

ascertaining an absence of acknowledgement of receipt of said first notice from said responsible party; and

periodically re-conveying said first notice in response to said ascertaining operation.

14. A method as claimed in claim 1 further comprising:

ascertaining an absence of acknowledgement of receipt of said first notice from said responsible party; and

forwarding said first notice to a second responsible party in response to said ascertaining operation.

15. A method as claimed in claim 14 further comprising performing said forwarding operation following expiration of an acknowledgement window, said acknowledgement window providing an interval during which said responsible party is to acknowledge said first notice.

16. A method as claimed in claim 1 further comprising:

receiving a disposition of said exception from said responsible party; and

retaining said disposition in a disposition database.

17. A method as claimed in claim 1 further comprising:

failing to receive a disposition of said exception from said responsible party; and

reminding said responsible party of said first notice.

18. A method as claimed in claim 1 wherein said apparatus is one of a plurality of apparatuses, said monitoring device is one of a plurality of monitoring devices, and said method further comprises performing said receiving, processing, determining, conveying, and preventing operations for each of said plurality of apparatuses at a common processing system.

19. A method as claimed in claim 1 wherein said apparatus is a transformer maintained by a utility company, said monitoring device is a dissolved gas monitoring unit, said data elements are current values of dissolved gases in transformer oil, and said method further comprises performing said receiving, processing, determining, conveying, and preventing operations at a processing system of said utility company.

20. A system for selective notification of a condition of each of a plurality of apparatuses, said each of said apparatuses being monitored by one of a plurality of monitoring devices, and said system comprising:

an analyzer configured for communication with each of said plurality of monitoring devices such that for said each of said monitoring devices, said analyzer receives data elements from said each monitoring device, processes said data elements to detect said condition of an associated one of said apparatuses, and determines that said condition defines one of a normal condition and an exception to said normal condition; and

a notification engine in communication with said analyzer, said notification engine conveying a first notice of said condition to a responsible party at a first instance of determination of said exception, said notification engine preventing conveyance of a second notice of said condition at a second instance of determination of said exception, said second instance occurring subsequent to said first instance, and said notification engine preventing communication with said responsible party upon determination of said normal condition.

21. A system as claimed in claim 20 further comprising a contact list database in communication with said notification engine for association of discrete responsible parties with fault conditions possible at said apparatuses, said exception defines one of said fault conditions, and said notification engine selects said responsible party associated with said one fault condition from said discrete responsible parties.

22. A system as claimed in claim 21 wherein said contact list database establishes a chain of authority of said discrete responsible parties for a plurality of severity levels of said one fault condition, said exception defines one of said severity levels, and said notification engine selects said responsible party associated with said one of said severity levels.

23. A system as claimed in claim 20 further comprising an acknowledgement database in communication with said notification engine for recording an acknowledgement from said responsible party of receipt of said first notice.

24. A system as claimed in claim 20 further comprising a disposition database in communication with said notification engine for retaining a disposition of said exception from said responsible party.

25. A method for selective notification of a condition of an apparatus monitored by a monitoring device comprising:

receiving data elements from said monitoring device;
