WebJun 1, 1999 · As the use of performance-based methods for evaluating the fire behavior of materials and systems becomes more widespread, objective criteria to judge fire behavior become more important. This paper reviews techniques for predicting the most common of these criteria, the onset of flashover. WebJul 1, 2016 · In the case of double circuit outages, majority of the flashovers occur at the same phase since both circuits are having synchronised AC voltages. The red phase of circuits 1 and 2 experiences flashover at the angle between 0° to 40° and 330° to 360° as the power frequency voltage of the red phase is the highest amongst the phases.
