ABSTRACT:
Apparatus and method are disclosed for testing winding terminations and more particularly for testing armature winding termination continuity. A nonrotating, simultaneous test is made of the armature winding terminations to commutator bars by simultaneously applying equal currents to different sets of bar-to-bar winding terminations. The differences in the bar-to-bar voltages of selected pairs of bar-to-bar terminations are obtained and a determination is made as to whether any voltage difference exceeds a reference limit. If not, then an acceptable continuity test indication is given.
