In this paper, the effect of signal conditioning on the performance of voltage dip detection is considered. In particular, root mean square based and a computationally light version of a Generalized Likelihood Ratio Test based voltage dip detector are compared. The effects of the conditioning on the detectors’ performance are analyzed, taking into account both frequency selectivity and error gains in the conditioning block. The usage of resistive-capacitive dividers and transformers to interfacing a single phase power signal to an acquisition system has been analyzed, using a Laplace domain based analysis.

Abstract
In this paper, the effect of signal conditioning on the performance of voltage dip detection is considered. In particular, root mean square based and a computationally light version of a Generalized Likelihood Ratio Test based voltage dip detector are compared. The effects of the conditioning on the detectors’ performance are analyzed, taking into account both frequency selectivity and error gains in the conditioning block. The usage of resistive-capacitive dividers and transformers to interfacing a single phase power signal to an acquisition system has been analyzed, using a Laplace domain based analysis.File in questo prodotto:
