This program was developed to aid research on non-sinusoidal current measurements. Specialised, well-defined waveforms could be created and used to excite the measuring device and by doing so the response of such a device could be determined by using a single experiment. The responses of a current transformer and a Rogowski coil were determined if they were to be used for current measurements in the presence of superimposed harmonics. Shown in the screenshot is a time domain waveform and frequency decomposition of the waveform.
