Patent ID: 8135550

Claim:
A method of identifying a relay, said method operable via a processor, said method comprising: coupling a first plurality of sensors to a relay trip ladder, wherein each of said first plurality of sensors is associated with one of a plurality of relays; collecting a first electrical data from said first plurality of sensors; identifying a trip signal on said trip ladder; determining a first relay of said plurality of relays from said first electrical data, wherein said first relay generated said trip signal; coupling a second plurality of sensors to a secondary side of a current transformer, wherein each of said second plurality of sensors is associated with one of said plurality of relays; collecting a second electrical data from said second plurality of sensors; determining a second relay from said second electrical data, wherein said second relay detected an electrical anomaly; and, generating an exception report indicating said trip signal and said identified relay, said exception report including a time, duration and description of the exception.
