IEC60112 IEC60335-1 IEC60598-1 Electric Leakage Tracking Index
Tester
Product information:
The tester is designed and manufactured according to the standard
requirements of IEC60112,IEC60335-1,IEC60598-1,UL746A and ASTM
D3638-92 . 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 (CTI) and
electrical resistance index (PTI).
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.
Leakage tracking tester 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. I t
is also suitable for the industry of insulating material,
engineering plastics, electrical connector and accessories.
