The article contains an overview of the type testing carried out for face shields used in Live Workings to protect against the thermal effects of electric arc flash. The main part of the article describes a workstation established for helmet resistance testing with an integrated face shield protecting against the thermal impact of an electric arc.
This paper presents the analysis of bidirectional Transient Voltage Suppressor (TVS) application for limitation of the electric arc energy in a low voltage circuit. The study employs both simulations and laboratory experiments, which were conducted to present inductive current breaking procedure with use of a standard switch and a switch with passive arc suppressor connected in parallel. EMTP-ATP...
