WebTo measure the material group of an insulator, a 0.1% ammonium chloride solution is applied to the material, and a voltage is applied across the insulator, allowing current to … 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 insulator, increasing current flow, resulting in increased heat generation, and eventually the insulation becomes completely condu…
