Inter-turn Short-circuit Detection Initial research studies proved that inter-turn short-circuits were one of the main root causes for insulation breakdown. As a consequence, since the early 80s a large number of researchers have focused their efforts in the early detection and diagnosis of this type of failure. In 1985 the WebInsulation failure in motor windings can be caused by interturn breakdown resulting from stresses generated by steep-fronted transient voltages. The production and severity of such transients and degree of voltage stress on the motor-winding insulation is governed by the characteristics of the overall system to which the motor is connected.
