Zařízení k testování chráničů pro možnost měření ochranné smyčky za proudovým chráničem

Abstract

This thesis addresses the issue of measuring the impedance of the protective loop downstream of a residual current device (RCD). The introductory section provides a theoretical description of the protective loop and the operating principle of the RCD. The following section analyzes the methods currently used to measure protective loop impedance, including an overview of available measuring instruments. The penultimate chapter focuses on the design and implementation of a test fixture intended for testing residual current devices. In the conclusion of the thesis, experimental measurements and testing of selected residual current devices are performed using this fixture.
