Liyi IEC60112 Comparative Leakage Current Tracking Index Tester
Product Description
It is used for the determination of comparative tracking indices of
solid electrical insulating materials on pieces taken from parts of
electrical and electronic equipment and on plaques of material
using alternating voltages. In normal use, components made of
insulating material may become moist and dirty. If the impurities
are electrically conducting, current will flow between parts of
different voltage potentials creating a track. As a result, small
flashovers may occur, which cause thermal stresses to the surface
of the insulating material. The visual result of thermal
decomposition of the insulating material caused by the tracking
current is called the track. The interconnecting formation of
carbonized material forms a tracking path, by which a lasting
current conducting connection results. Thereafter the component
cannot fulfill its intended electrical function in the majority of
cases and parts may catch fire. The resistance of an insulating
material to track formation is called the tracking resistance.
Principle:
The leakage tracking tester meets theIEC60112test standard. A rectangular platinum electrode was used, and the
force of the two poles on the sample was 1.0 N; 0.05 N,
respectively. The applied voltage is adjustable between 100 and
600V (48-60Hz), and the short-circuit current is 1.0; 0.1A, the
voltage drop should not exceed 10%. When the short-circuit leakage
current is equal to or greater than 0.5A in the test circuit, the
time is maintained. 2 seconds, the relay is activated, the current
is cut off, indicating that the test piece fails. The time constant
of the drip device is adjustable, and the amount of drip is
controlled to be 44 to 50 drops/cm3 and the time interval between
drops is 30 seconds.
