3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 With impulse voltage test motor windings (or coils) A method of interturn insulation. The principle is to have a predetermined peak and front time of impulse voltage wave (or both) are alternately applied directly to the same design subjects Product and the reference winding (or coil), using impulse voltage caused in both attenuation oscillation waveform whether there are differences, to detect the motor windings (or Coil) inter-turn insulation is good. 3.2 A rotary motor having a predetermined function of a set of turns or coils. 3.3 Or a component having a plurality of coil elements, typically having a common insulation. 3.4 When the shock wave shape comparison with interturn insulation was used to detect the motor windings (or coils), for electrically tested winding (or coil) is compared with the Machine windings (or coils). Reference winding (or coil) of the parameters must be tested winding (or coil) identical. Reference winding (or coil) can optionally at the same motor, the motor can also be optionally in the same specifications. Reference winding (or coil) can be recognized as an inter-turn insulation is assumed to be normal or normal winding (or coil). ......
