ComparativeTracking Index Apparatus

CTI Comparative Tracking Index test apparatus is a versatile device. This device is designed to meet the requirement of Indian and International for basic testing of determining comparative tracking index of solid insulating materials under moist conditions. It is very easy to understand the working of the device. The inner body of the apparatus is made up of stainless steel & outer body is made up of mild steel. The reset switch is also available on the panel, where you can preset the desired no. of drops as per requirement. Tracking test indicates the relative resistance of solid insulating electric materials when submitted up to required test range. This method exposes the tested object to electric stress under water action with contaminant addition tracking may occur during test when voltage is activated on a defined disposition of electrodes on the material surface and electrolyte drops of salt solution are injected during a definite interval of time. The number of necessary drops to cause damage on the material increases with the reduction of the applied voltage. Under a critical value, tracking does not occur.
