Equipment Overview
The tester is designed and manufactured according to the standard
requirements of IEC60112, and required by IEC 62196-1Ed.4CDV 2020
clause 28.4, 29.6, IEC60335-1 clause 29.2 and Annex N, IEC
60065:2014 clause 13.4, IEC60598-1, IEC 60884-1:2013 clause 28.2,
UL746A and ASTM D3638-92 and etc. 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).
A gauge block is supplied with the instrument to ensure the
electrodes have the proper distance between them. The table height
is easily adjustable to ensure the proper angle of the electrodes
and height of drops. The rest of the test is controlled from
outside the test chamber with the door closed. The voltage,
limiting current, drip rate and number of drips are all set on the
control panel. An operator should observe the test to see if a
flame ignites. The instrument sounds an alarm if there is a
tracking failure of at least two seconds.
The leakage tracking tester adopts to advanced PLC control system
and 7” color touch screen, it is suitable for the research,
production and quality department of lighting equipment,
low-voltage apparatus, household appliance, machine tool electric
appliance, electrical machine, electric tool, electronic
instrument, electrotechnical instrument, information technology
equipment. It is also suitable for the industry of insulating
material, engineering plastics, electrical connector and
accessories.
