scope:

This guide is based on the knowledge and experience accumulated over a decade of using the inclined plane tracking and erosion test setup with direct current (dc) voltages for the evaluation of tracking and erosion resistance of outdoor insulating materials. This guide discusses various important aspects that need to be considered for conducting a feasible test under dc voltages. However, it must be clear that judgment and experience are required to analyze and balance the discussed aspects for any specific application of the dc inclined plane tracking and erosion test.

Purpose

This guide is intended for a suitable use of dc voltages with the inclined plane tracking and erosion test for the evaluation of the tracking and erosion resistance of high voltage outdoor insulating materials.
