PROBLEM TO BE SOLVED: To provide a calibration method for enhancing a measurement accuracy of one or more voltage sensing devices in the presence of a plurality of conductors.SOLUTION: The method includes operatively coupling the voltage sensing devices to corresponding conductors of the plurality of conductors, and determining sensed voltage values of the corresponding conductors using the voltage sensing devices. The method further includes determining a calibration matrix having cross-coupling factors representative of cross-coupling between an antenna of the voltage sensing devices and other conductors of the plurality of conductors, and determining corrected voltage values of the corresponding conductors by deducting contributions of the cross-coupling from the sensed voltage values of the corresponding conductors using the calibration matrix. |
