Tracking Index Test Machine from SCR ELEKTRONIKS is a popular product for checking compliance of solid insulating material as per IEC 60112, UL 746A, ASTM D3638 and DIN 53480. With a high voltage applied between two platinum electrodes, the solid insulating part is placed such that there is a 4mm gap between the electrodes touching the insulating material under test. The high voltage is settable up to 600V or 1200V depending on model. Drops of contaminant are poured on to the electrodes while voltage is applied. With time, it’s evaluated on the criteria outlined in IEC 60112 or the equivalent national standard with which the insulating material is required to comply with.
The tracking index test provides an accelerated simulation of conditions of surface discharges and possible resulting tracking and failure in equipment using insulating materials. This test also provides a means to compare insulating materials performances under wet and contaminated conditions.
