1, Applicable scope:
The leakage trace tester is a device that applies a certain voltage between platinum electrodes of a specified size (2mm x 5mm) on the surface of solid insulation materials, and drops a specified volume of contaminated liquid (0.1% NH 4 CL) at a fixed height (35mm) for 30 seconds to evaluate the tolerance of the surface of solid insulation materials under the combined action of electric field and contaminated medium, and to determine its relative tracking index (CTI) and resistance to tracking index (PTI).
Suitable for research, production, and quality inspection departments of lighting equipment, low-voltage appliances, household appliances, machine tool appliances, motors, electric tools, electronic instruments, electrical instruments, and information technology equipment, as well as insulation materials, engineering plastics, electrical connectors, and accessory industries.
