Investigating inter-turn fault in transformer using TTR and FRA
… deformation, tap changer damage, and short turns (inter-turn fault). The transformer inter-turns fault reduces the number of turns in the winding. To detect inter-turn fault, the transformer turn ratio test is the basic method used. On the other hand, frequency response analysis has been …

Impact analysis of motor faults on the DC Bus in electric vehicle drivetrains
… vehicle drivetrains in the presence of a motor fault within a powertrain. The investigation was conducted utilizing a test rig that facilitated the controlled implementation of known faults in induction motors connected to an electric vehicle powertrain configuration, thus enabling the …

Application of Sweep Frequency Response Analysis and Locked-Rotor Test for Stator Winding Inter-Turn and Broken Rotor Bar Fault Detection of Squirrel-Cage Induction Motors
… to various types of failures due to external or internal factors. Several studies have shown that 30%-40% [3], [4] and 5- 10% [5], [6] of the total failures of induction motor are due to the stator winding breakdown and rotor failures, respectively. Most induction motors have a long service life …
