The Comparative Tracking Index Tester is used to test the resistance to tracking of solid insulators or parts of insulators used in electrical appliances and accessories. This test is mandatory for manufacturers of most of the electrical products such as circuit breakers, meters, switches, sockets, plugs, starter holders, connectors, etc.
Built in electrolyte container with pump, producing drops of 20 + 3 mm3 volume at precise interval of 30 seconds. The drop falling height is adjustable to 35 mm.
Priming facility for the pump to enable removal of initial electrolyte having higher concentration.
Fully automatic unit with minimum of controls & adjustments.
Micro-controller based timer control unit used to set the timings and to control the sequence of operations.
Pre-set load on the electrodes with a force of 1.0 N each.
Short circuit release – 0.5 A for 2 sec; Short circuit current limited to 1 A.
Electrode Voltage Settings – 0 to 230V, 0 to 350V, 0 to 450V, 0 to 550V, 0 to 650V adjustable.Current limiting resistances automatically selected with test voltage.
