7. Comparative Tracking Index - Wikipedia

   en.wikipedia.org/wiki/Comparative_Tracking_Index

   The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material. Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material. The carbonized areas are more conductive than the pristine ...
