The Time Response Analysis of a Hybrid Electronic Switch and Residual Current Devices System

Abstract

Residual current devices are vital as they are used to protect humans from electric shocks and fire hazards. These devices detect the residual current in the grid, open the mechanism, and leave the grid without voltage. In this study, the time response of a newly designed hybrid system consisting of an electronic switch system and a residual current device to protect humans from hazards has been analyzed. A model consisting of capacitors and resistors has been used to simulate the human body. In the designed system, the average response time was found to be 1.37 ms, which operates with an average of 6.43 times faster than a conventional residual current device. The results of the study illustrated that the designed system leaves the circuit voltage-free much faster than a conventional residual current device and is more effective in protecting human life. © 2024, Strojarski Facultet.
