Detekce přítomnosti elektrického napětí při zdolávání specifických mimořádných událostí

Abstract

This diploma thesis addresses the issue of electric voltage detection during fire and rescue operations, particularly in connection with the development of electromobility, photovoltaic systems, and battery storage technologies. The aim of the thesis is to propose an appropriate set of technical tools for detecting and measuring the presence of alternating and direct electric voltage in the context of specific emergency incidents.

The theoretical part focuses on explaining the physical principles of electric voltage, classifying its sources, and outlining the relevant legislative framework. The practical part analyzes the current state of detection equipment used by the Fire Rescue Service of the Czech Republic, industrial fire brigades, and selected foreign fire services. The thesis also includes a market survey and practical testing of a selected non-contact direct voltage detector under real-world conditions. The outcome is a proposed composition of suitable detection tools and recommendations for their deployment in incidents involving the presence of electric voltage.
