dc.description.abstractArching faults which endanger the personnel and equipment near to its vicinity must be controlled so that we have high power quality, more security as well as more reliability in power systems. Therefore careful study of electric arc behavior in air is needed, more specifically how different parameters which affect reignition, behave near current zero. A lot of research has been done, finding this behavior near current zero, in order to have better understanding of when interruption is possible, but generally those were concentrated on looking, this behavior, after arc interruption. In this thesis, a different approach has been used to find the arc behavior near current zero. Basically indirect parameters of arc model has been found out, 15 micro seconds before current zero, which tells the conductivity decay at that instant and Mayr Arc Model has been used to find out these parameters. Dependence of breakdown voltage of air, on temperature has also been investigated and different electrode materials have been used in order to see electrode material dependence on breakdown voltage at a specific temperature of gap space.fi
