Tracking index tester
Introduction
The electric tracking index test is performed on a surface of a solid insulating material by applying a voltage to a platinum electrode of a predetermined size (2 mm x 5 mm) and dropping a predetermined volume of conductive liquid (0.1% NH 4 Cl) at a predetermined height (35mm) for 30 seconds, to evaluate the electric leakage resistance performance of the surface of a solid insulating material under the combined influence of an electric field and a wet or contaminated medium.
Tracking index tester rigorously is a professional inspection tester, designed and manufactured based on GB4207, IEC60112 and other standard, to measure the comparative tracking index and proof tracking index in the simulated wet condition, with characteristics of simplicity, accuracy, reliability, practical feature, etc.
Application
Tracking index tester is suitable for the research, production and quality inspection departments in the industry of lighting equipment, low-voltage electrical appliances, household appliances, machine tools, electrical machine, electric tools, electronic instruments, electro technical instruments, information technology equipment, as well as insulating materials , engineering plastics, electrical connectors, accessories industry.
