dc.descriptionAn arc flash refers to an electrical explosion that might happen when there is a sudden and intense flow of current, occurring either between a conductor and the ground or between two conductors. Arc flashes produces intense heat and light, and can release large amounts of energy.
dc.description.abstractAn arc flash refers to an electrical explosion that might happen when there is a sudden and intense flow of current, occurring either between a conductor and the ground or between two conductors. Arc flashes produces intense heat and light, and can release large amounts of energy. Arc flash analysis is required to quantify the associated risk and minimize the possible consequences with optimal protective measures. The electrical power system in Nepal is in growing phase. There are number of substations being upgraded, new substation being constructed. However, the consideration of arc flash analysis in substation protection system are not found to the level it required. The primary goal of this study is to quantify possible risks linked with arc-flash incidents in the Attariya Substation, and devise effective mitigation techniques. There were unofficial record of number of incidents related to arc flash in Attariya substation such as fire in low voltage switchgear and arcing due to underground cable termination explosion. The transformers in Attariya substation has been upgraded with higher capacity, which might have resulted in higher fault level in the substation.
