<1000KN Pti / CTI Wire Cable Tracking Index Test Machine
>0.5m3 , Black Interior
Product Description:
Pti / CTI Wire Cable Tracking Index Test Machine 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.
Pti / CTI Wire Cable Tracking Index Test Machine is a fully automatic instrument contained in its own cabinet to
maximize the safety of the operator.Inside the well lit cabinet, a
test specimen is placed on a glass plate and two platinum
electrodes are lowered onto the top surface.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.
