Overview
The LISUN High Voltage Tracking Test Chamber evaluates the high-voltage tracking resistance of insulating materials using contaminant solutions at elevated voltages. The Comparative Tracking Index (CTI) and Proof Tracking Index (PTI) are determined by monitoring whether tracking or flash-over occurs under specified test conditions. Used for insulating materials in high-voltage equipment including power supplies, inverters and switchgear.
