Patent ID: 8084891

Claim:
A method for optimizing switching operations executed by a switching device operatively coupled to an AC power line, the method comprising: a) acquiring signals related to the waveform of the electrical phases of said AC power line; b) when a command for executing a switching operation on at least one of said electrical phases is issued, storing signals acquired for said at least one of said electrical phases for a predetermined period of time; c) calculating first data indicative of the time occurred for the executed switching operation; d) calculating second data indicative of the severity of switching transients occurred during the executed switching operation, wherein said calculating second data comprises subtracting signals representative of the steady state waveform of the at least one electrical phase from the stored signals, resulting in transient signals of the at least one electrical phase; e) based on at least said first and second data calculated for the executed switching operation, determining if a predefined parameter representative of a target point on the waveform for executing future switching operations substantially synchronous with said waveform has to be adjusted.
