Applicable industriesThe electric trace index tester is suitable for research, production, and quality inspection departments of lighting equipment, low-voltage electrical appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, and information technology equipment. It is also suitable for industries such as insulation materials, engineering plastics, electrical connectors, and accessories.

Test method: On the surface of a solid insulation material, a certain voltage is applied between platinum electrodes of a specified size (2mm × 5mm), and a specified droplet volume of contaminated liquid (0.1% NH 4 CL) is dropped at a fixed time (30s) and height (35mm) to evaluate the tolerance of the solid insulation material surface under the combined action of electric field and contaminated medium. The relative tracking index (CT1) and tracking resistance index (PT1) are measured

Applicable standards: IEC6012:2003, GB4706.1, and GB/T5169.4 GB2099.1、VDE、 The simulation test items specified in the standards for the determination method of the electrical trace resistance index and the comparative electrical trace index of solid insulation materials.
