Patent ID: 8457910

Claim:
A method for analyzing an electrical power system which includes at least one line carrying electrical power between a generating station and a customer, comprising: (a) acquiring data representing one or more line parameters of the electrical power being carried on the electrical power system; (b) using an electronic computing device, identifying a power system event within the data by: (1) establishing one or more selection criteria; (2) evaluating the data to determine if the one or more selection criteria are satisfied, (3) when one or more of the criteria are satisfied, declaring that a power system event is present; and (4) storing a data window representing a portion of the data containing the power system event; (c) using the computing device, analyzing the data contained in the data window; (d) based on the analysis, associating the power system event with a root cause from among a plurality of possible root causes, where the root cause is an incipient or actual failure within the electrical power system; and (e) using the computing device, suggesting a remedial action for the electrical power system consistent with the type of incipient or actual failure determined to be present.
