Tracking tester I. Product Overview: 1, tracking test (tracking index test) is a reference to the IEC60112, GB / T4207, UL 746A, GB4706.1 ASTM D 3638-92, and other domestic and international safety standards The simulation test project. 2. Tracking test (tracking index test) is on the surface of solid insulating material between the required size (2mm × 5mm ± 0.1mm) platinum electrode, applying a voltage and timing (30s) set height ( 35mm) dropping the provisions of conductive liquid droplet volume (0.1% NH 4 CL), to evaluate the resistance of solid insulating material surface leakage performance in the electric field and the combined effects of wet or contaminated media, and measured the comparative tracking index (CTI ) and resistance to tracking index (PTI). 3. Tracking tester (tracking index tester) instrument for research lighting, low voltage electrical appliances, household appliances, electrical machines, motors, power tools, electronic equipment, electrical instruments, IT equipment, production and quality inspection department, but also for insulation, plastic, electrical connectors, accessories industry.
