Leakage Tracking Tester LT-3 0～600V Adjustable Precision 1.5％
Standard of Leakage Tracking Tester:
IEC60112-2009, UL746A, IEC60335-1, IEC60598-1 and ASTM D3638-92.
Application of Leakage Tracking Tester:
It is used to 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 compare tracking index (CT1) and
electrical resistance index (PT1).
Test Sample of Leakage Tracking Tester:
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 of Leakage Tracking Tester:
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) drops
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
surface under the combined influence of electric field and humid or
contaminate medium. In a word, this device is used to measure the
compare tracking index (CT1) and electrical resistance index (PT1).
