Method for determining error of electrical network of electric installation plant installed in building, involves determining set of coefficients from frequency distribution of current flow interruption time intervals

摘要

The method involves determining current flow interruption time intervals (At) based on time-current characteristic over a predetermined period. The frequency distribution of the current flow interruption time intervals is determined. The set of coefficients are determined from the frequency distribution of current flow interruption time intervals. The property of the electric network is determined from the set of coefficients. An independent claim is included for analysis device.
