Tracking Index Apparatus For High Voltage Leakage

What is the Tracking Index Apparatus For High Voltage Leakage？

The Tracking Index Apparatus for High Voltage Leakage is designed to evaluate the electrical tracking resistance of insulating materials under high voltage conditions. This apparatus applies a controlled voltage across a test specimen while simultaneously introducing a conductive liquid, simulating conditions that promote tracking and potential failure. It measures the time until tracking occurs and assesses the material's ability to withstand leakage currents, providing essential data for evaluating the safety and reliability of insulation in electrical applications.

compliance: IEC60587:2007 "Electrical insulating materials used under severe ambient conditions—Test methods for evaluating resistance to tracking and erosion".
