Scope of application:

     The tracking tester is suitable for the research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, power tools, electronic instruments, electrical instruments, and information technology equipment, as well as insulating materials, engineering plastics , electrical connectors, accessories industry.

Standards compliant:

    IEC60112: 2003 "Method for Determination of Tracking Resistance Index and Comparative Tracking Index of Solid Insulating Materials", UL746A,

Simulation test items specified by ASTMD3638-92, DIN53480, GB4706.1 and GB4207 standards.

Fundamental:

    Under the influence of humidity and impurities in electrical products, there may be leakage current on insulation between live parts of different polarities or between live parts and grounded metal, and the resulting arc may cause breakdown and short circuit to the electrical appliance or electrical corrosion of materials due to discharge. damage, or even ignite causing a fire. The tracking tester is a destructive test that simulates the above situation on insulating materials. The test is to apply a certain voltage on the surface of the solid insulating material between platinum electrodes of a specified size (2mm × 5mm) and drop the polluted liquid (0.1% NH 4 CL), to evaluate the resistance of the surface of the solid insulating material under the combined action of electric field and polluting medium, and measure its comparative tracking index (CT1) and tracking resistance index (PT1).
