Used range
This machine applies to determine the tracking index for electrics
of various products, such as lighting, electronics, electric tools
and instruments. It is also used for insulators, plastics, electric
connectors and so on.
Principle
In moisture and impurity circumstance, leakage current of
insulation will be produced between live parts of different
polarity, or between live parts and grounding metals. The electric
arc produced will result in short-circuit. This tester is to
simulate these conditions, and to determine the tracking index of
materials.
