Working principles :
The leakage tracking test(tracking index testing) is that the conducting liquid (0.1%NH 4 CL) of required volume in the required height (35mm ) and required time (30s) drops with the voltage between the platinum electrodes(2mm × 5mm )on the surface of solid insulating material.
Determination:
Thus the users evaluate the tracking resistance performance of solid insulating material surface under the combined influence of electric field and humid or contaminate medium. In a word, this device is used to measure the comparative tracking index (CTI) and the proof tracking index (PTI).
