Method for automatic characterization and monitoring of electrical system by comparing correlations between measured values, involves performing comparison through evaluation of mutual correlations of pairs of measurement variables

摘要

The method involves performing comparison through evaluation of mutual correlations of pairs of measurement variables (1). Multiple currently measured pairs of measurement values of all evaluated pairs of measurement variables are checked to see whether they lie within the expected range limits (8'), which are obtained from multiple historical pairs of measurement values of all evaluated pairs of measurement variables. An independent claim is included for a device for automatic characterization and monitoring of an electric network or a power network section of an electric network or an electrical system by comparing correlations between measured values.
