摘要

calibration method to improve measurement accuracy, method for detecting individual voltage values and monitoring system. This is a calibration method for improving the measurement accuracy of one or more voltage pickup devices in the presence of a plurality of conductors. The method includes operably coupling at least one voltage pickup device from one or more voltage pickup devices to a respective conductor of the plurality of conductors and determining a voltage value captured from the respective conductor using the at least one voltage pickup device. tension. further, the method includes determining a calibration matrix having representative cross-coupling factors between an antenna of the at least one voltage pickup device and other conductors within the plurality of conductors and determining a corrected voltage value of the respective conductor. at least in part by deducting contributions from the cross coupling from the voltage value captured from the respective conductor using the calibration matrix.
