The leakage flux around the core will be very high ( max) during Short Ckt test , whuich will have a factor of overhaeting , more at corners and edges .Hopwevr thge basic fcator is early saturation of core which gives rise to reduction of impedence that generates high ( very high ) current in the winding causing the failures
