Data acquisition system for testing the insulation between the stator laminations of high power electrical machines

The paper presents fault detection equipment used for insulation testing between the stator laminations of high power machines. To give more flexibility of a measurement system, a software component must take in consideration. This paper complete previously theoretical model developed. The equipment presented provides the opportunity to test the insulation between the stator laminations of electric machines for a wide power range with a clear diagnosis of the presence of defects in insulation between the stator laminations. The paper focuses on virtual instrument, data acquisition, control, and interface on the acquired signals.
