Abstract (Swedish)
This study aimed to evaluate the use of Pyrotechnically Generated Aerosols in electrical fires. To
represent a common starting point for these fires, a cable fire ignited by a shortcut was chosen. In
order to do this in a realistic way, a new method with heating the cables from the inside was used. This
study examined whether the PGA has the ability to supress a cable fire inside an electrical cabinet and
how the PGA activation affect the pressure in the compartment. It was found that PGA grenades can
be used to extinguish a cable fire inside an electrical cabinet. It was also found that more grenades are
not always better and that simultaneous activation is not recommended. The method regarding heating
cables from the inside was... (More)
