Timing-shift similarity calculation betweenthe sampling signal sequence of the monitoring device and the output signal sequence of standard source has beencarried out so as to analyze calibration signal synchronization method and its composition. Output method ofheterogeneous calibration signal has been considered in the case of the whole point sampling and random samplingof the monitoring device. In addition, the calibration software about power quality monitoring devices is developed tomeasur |
