Educational MS Excel application for processing database of measured nonsinusoidal waveforms of electrical quantities

Abstract

The contribution describes MS Excel program application for parameters determination of an electric circuit in the nonsinusoidal steady state. The parameters of the series or parallel circuit model are calculated over a time period T of measured voltage and current waveforms by means of a new method. The calculated parameters are constant coefficients of an integro-differential equation of the model circuit. The measured voltage and current are acquired by means of the digitizing oscilloscope TDS 420 from Tektronix. Widespread MS Excel environment is utilized for processing and visualization of time waveforms and results.
