AC Arc Flash Analysis

Abstract

This diploma thesis explores Arc Flash Analysis for AC networks further into the topic of electrical safety and as the continuation of load flow, short-circuit, and selectivity studies on power systems. The thesis contains two main parts of the research. The first part describes the theoretical background of the Arc Flash Analysis and acts as the quintessence of information from several standards, concerning the arc flash hazards. The second part presents an example of performing the Arc Flash Analysis on a power system from one of ABB EUOPC projects, including mitigation measures. The main goals of this work are to provide full algorithm on how to perform Arc Flash Analysis and to look deeper into the way how ABB EUOPC is dealing with complications of the topic.
