Leakage Trace Tester It Is Applicable To Research, Production And Quality Inspection Departments Of Lighting Equipment, Low-Voltage Electrical Appliances

I. Scope of Application
The tracking test instrument is used to apply a certain voltage between platinum electrodes of specified dimensions (2mm×5mm) on the surface of solid insulating materials, and then drop a specified volume of contaminated liquid (0.1%NH 4 CL) at a fixed height (35mm) at regular intervals (30s). It is used to evaluate the surface resistance of solid insulating materials under the combined action of electric fields and contaminated media, and to determine their comparative tracking index (CTI) and tracking resistance index (PTI).
It is applicable to research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, electric tools, electronic instruments, electrical measuring instruments and information technology equipment. It is also applicable to the insulation materials, engineering plastics, electrical connectors and accessories industries.
