Understanding Parametric Graphs-1

Read why parametric graphs are useful for waveform analysis.


Parametric graphs present a little-seen view of load waveforms.


By graphing the current waveform against the voltage, a voltage-independent load signature can be established.


This is useful for characterizing load properties, and establishing a baseline signature for comparison with future recordings.


Voltage and current waveform data is most often presented as two time series, plotted with instantaneous voltage and current values on the y-axis, and time on the x-axis...
