Patent ID: 7698582

Claim:
An intelligent electronic device for communication with a power system element for protection, monitoring, controlling, metering or automation of a portion of an electrical power system, said power system element communicating a data signal related to a select event associated with the power system element to the intelligent electronic device, the intelligent electronic device comprising: a sequential events recorder to receive the data signal and record the select event associated with the power system element, a clock in communication with the sequential events recorder, said sequential events recorder associating a time with the select event based on the clock, a debounce timing element for detection and compensation of bouncing in the data signal, said debounce timing element producing a delay in the receipt of the data signal by the sequential events recorder, and a time delay element coupled to the sequential events recorder, wherein the time delay element compensates for the delay produced by the debounce timing element such that the sequential events recorder records a compensated time for the select event based on the clock and the time of day.
