Analysis and selection of current and voltage transformers for reconstruction of HPP Zakucac
Abstract
The paper presents the calculations and selection of parameters of current and voltage transformers of the generator voltage level of the new generators for HE Zakucac. When selecting the protective cores of the associated current transformers, due to the proximity of the generator itself, analyzes of their dynamic behavior in the event of a three-pole short circuit were performed. In this sense, the necessary data on the oversizing coefficient, the resistance of the secondary winding and the saturation voltage of the current transformers were defined, among other things.
