- Abstract:
- The paper analyses the random components influence on the values characterising periodic disturbances in the supply line voltage on the example of the total harmonic distortion coefficient (THD). It presents the method to determine the uncertainty in the THD coefficient measurement, which takes into account the correlations appearing between the fundamental component and the successive harmonics of the supplying voltage, and also between particular harmonics. The analysis of the results from the total harmonic distortion coefficient measurements in the supplying voltage of a motor drive system with the electronic power converter is presented.
