Continuous, Inline Testing of Magnet Wire Products: Advantages and Considerations

The traditional method of quality control testing of magnet wire, consists of a withstand (high potential) testing of a reel of wire per NEMA MW 1000, which is typically performed using a batch process. This paper explores an inline testing method using a spark testing system that has been historically utilized for wire and cable quality control testing. The two methods employ different detection styles. The pros and cons of the two methods will be reviewed.
