Abstract
A method and an apparatus for optimizing switching operations executed by a switching device coupled to an AC power line, wherein signals related to the waveform of the electrical phases of the power line are acquired. When a command for executing a switching operation on one of the electrical phases is issued, the signals acquired are stored. Based on the signals stored, data indicative of the severity of switching transients occurred during the executed switching operation and second data indicative of the time occurred for the executed switching operation are calculated and correlated to each other. Based on the data calculated, it is determined whether a parameter representative of a target point on the waveform for executing future switching operations substantially synchronous with the waveform has to be adjusted.
