CALIBRATION METHODS FOR VOLTAGE SENSING DEVICES |
摘要 |
A calibration method for enhancing a measurement accuracy of one or more voltage sensing devices (100) in presence of a plurality of conductors (102) is provided. The method includes operatively coupling at least one voltage sensing device (100) of the one or more voltage sensing devices to a respective conductor of the plurality of conductors (102) and determining a sensed voltage value of the respective conductor (102) using the at least one voltage sensing device (100). The method further includes determining a calibration matrix having cross-coupling factors representative of cross-coupling between an antenna (110) of the at least one voltage sensing device (100) and other conductors of the plurality of conductors (102) and determining a corrected voltage value of the respective conductor (102) by deducting at least in part contributions of the cross-coupling from the sensed voltage value of the respective conductor (102) using the calibration matrix. |
