Information Circular 9120: Fuse Wire Arc Tester

Details

• Personal Author:
  Kovalchik, Peter G.
• Description:
  To compare the viability of the new fuse wire arc test (fwat) as a substitute for the comparative tracking index (cti) for determining surface resistance to electrical tracking, the Bureau of Mines constructed a fuse wire arc tester and undertook a detailed testing program for testing insulating materials used on explosion-proof enclosures. This report describes the Bureau's apparatus, the two methods (cti and fwat), and the results of the Bureau's testing, showing comparisons of the fwat with the cti. Results showed strong correlation between the two methods, as all specimens tested that had cti rating of 400 V ac rms and above passed the 10-test sequence with the fwat, whereas all specimens with lower cti ratings failed, with the number of tests to failure corresponding roughly to the descending cti rating order.
