  • Cable fault detection
    Patent number: 7725295
    Abstract: A cable fault detection component (168) receives input data indicative of a fault in an electrical power system. The component (168) analyzes the input data to determine if the fault is indicative of a temporary or self-clearing cable fault and generates corresponding output data (276). In one implementation, the cable fault detection component (168) is implemented as a software module which operates on a computer (105) of a substation intelligence system (104).
    Type: Grant
    Filed: April 30, 2009
    Date of Patent: May 25, 2010
    Assignee: ABB Research Ltd.
    Inventors: James Stoupis, Ajay C. Madwesh, David Lubkeman, Mirrasoul Mousavi

  • Electrical substation monitoring and diagnostics
    Patent number: 7558703
    Abstract: A substation intelligence system (104) includes a substation computer (105) which is operatively connected to a plurality of field devices (102) through an input/output subsystem (204). Data indicative of the devices is stored in a substation database (208). Advanced monitoring and/or diagnostics (107) use information from the database to perform various monitoring and/or diagnostic functions.
