Comparative Tracking Index Tester for Electrical Insulating Materials .
Product details: Model ZLT-LDQ:
The ZLT Tracking Tester is used for the determination of comparative tracking index of solid electrical insulating materials on pieces taken from parts of electrical and electronic equipment and on plaques of material using alternating voltages.
The ZLT Tracking Tester 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.
Platinum is specified as a material for the electrodes. The power supply unit is designed for voltages up to 600 V, or up to 1000V. An electronic control unit serves for releasing the drops.
In the case of the ZLT tracking tester, the electrode arrangement is mounted in a stainless steel cabinet. By a glass door, a good accessability of the testing arrangement ensurws a pleasant working. A safety system breaks the supply when the cabinet is opened.
