Solid Insulating Materials Proof and Comparative Tracking Indices Testing Equipment PLC Control Tracking Test Chamber
Overview:
This tracking leakage testing equipment is designed according to IEC 60112. It is used for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages.
If electrical products affected by moisture and impurities environmental, leakage may be caused on the insulation between different polarity live parts or live parts and grounded metal, the generated arc will cause short circuit or electrical erosion due to discharge, even cause fire. The tracking test is a destructive test to insulating material simulating the above situation, to measure and assess the relative resistance to tracking when the insulator is in the effect of electric and impurities in water-containing.

What's the concept of Proof and Comparative Tracking Indices?
Comparative Tracking Index (CTI):
Numerical value of the maximum voltage at which five test specimen withstand the test period for 50 drops without tracking failure and without a persistent flame occuring and including also a statment relating to the behaviour of the material when tested using 100 drops.
Proof Tracking Index (PTI):
Numerical value of the proof voltage in volts at which five test specimens withstand the test period for 50 drops without tracking failure and without a persistent flame occuring.
