The aim of the paper is to present a response on dips and on interruptions of the measured voltage by means of electronic voltage transducers and inductive voltage transformers. Results of laboratory studies show high overvoltages generated in both a primary and secondary side of inductive VTs during the above mentioned conditions. Overvoltages in secondary circuits may damage measuring or protection apparatus connected to the secondary side of the VT. Using electronic voltage transducers enables users to avoid these problems.
