On a solid surface of insulating material, between the required size (2mm * 5mm) platinum electrode, a voltage is applied. At the same time, timed (30s), set height (35mm) and dropping a predetermined volume of contaminated liquid droplets (0.1% NH 4 CL ) to evaluate the endurance capacity of the surface of solid insulating materials under the combined effects of electric and contaminated media, accordingly, its comparative tracking index (CTI) and resistance to tracking index (PTI) is tested.
Comparative Tracking Index Tester suitable for the research, production and quality control for lighting, low voltage electrical appliances, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instruments, information technology equipment, and also suitable for insulation, plastic, electrical connections, accessories industry.
