This Tracking Index apparatus is a fully automatic instrument contained in its own cabinet to
maximize the safety of the operator and mainly used test the resistance Tracking Performance
of solid electrical insulation materials when they are exposing in electric affect impurity water
situation.Mainly used for determination PTI and CTI items.
Inside the well lit cabinet, a test specimen is placed on a glass plate and two platinum electrodes
are lowered on 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.
