Standard
IEC60112-2009, UL746A, IEC60335-1, IEC60598-1 and ASTM D3638-92.
Application
The leakage tracking tester is used to evaluate the tracking resistance performance of solid insulating material surface under the combined influence of electric field and humid or contaminated mediums. In a word, this device is used to measure the comparison tracking index (CT1) and electrical resistance index (PT1).
Test Sample
Lighting equipment, low-voltage electrical appliances, household electrical appliances, machine tools, electrical appliances, electric motors, electric tools, electronic instruments, electrical instruments, information technology equipment, insulation materials, engineering plastics, electrical connectors, accessories industry.
Feature
The working principle of 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) drop s with the voltage between the platinum electrodes (2mm× 5mm )on the surface of solid insulating material. Thus the users evaluate the tracking resistance performance of solid insulating material under the combined influence of electric field and humid or contaminate medium.
