Tracking Index Tester

Pengantar
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.

Test principle:
A conductive liquid (0.1% by weight) having a predetermined droplet volume was dropped onto the surface of the solid insulating material and a platinum electrode of a predetermined size (2 mm × 5 mm) by applying a voltage and dropping a predetermined height (35 mm) NH 4 CL) was used to evaluate the leakage resistance of the surface of the solid insulating material under the combined effect of electric field and moisture or contaminating medium. The relative electrical tracing index (CT1) and the resistance to tracing index (PT1)
