Equipment failure detection in an electric power system

A system to detect a failure in an electric power system, the system comprising:

• a communication interface to receive:
• a first indication related to a condition in the electric power system;
• and
• a second indication related to the condition;
• a test subsystem to:
• compare the first indication to the second indication;
• determine a discrepancy between the first indication and the second indication;
• a diagnostic subsystem to identify the failure based on the discrepancy between the first indication and the second indication;
• and
• an alert subsystem to generate an alert based on the failure;
• wherein:
• the first indication comprises a status of an output contact;
• the second indication comprises a measurement of a condition associated with the status of the output contact;
• and
• the diagnostic subsystem identifies the failure based on a difference between the status of the output contact and the condition associated with the status of the output contact.

• an alert subsystem to generate an alert based on the failure;
• and
• a condition-based monitoring subsystem to:
• receive information over time regarding operation of a piece of equipment in the electric power system;
• perform a predictive analysis based on the information;
• and
• generate an assessment of a remaining useful life of the piece of equipment.

A method for detecting a failure in an electric power system, the method comprising:

• receiving a first indication related to a condition in the electric power system;
• receiving a second indication related to the condition;
• comparing the first indication to the second indication;
• determining a discrepancy between the first indication and the second indication;
• identifying the failure based on the discrepancy between the first indication and the second indication;
• and
• generating an alert based on the failure;
• wherein:
• the first indication comprises an input to a protective relay;
• the second indication comprises an output from the protective relay;
• and
• identifying the failure based on a difference between the output from the protected relay and an expected output from the protective relay based on the input.
