IEEE Std 2652:2021 pdf download.IEEE Guide for DC Inclined Plane Tracking and Erosion Test for Outdoor Insulation Applications.
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.
1.2 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.
1.3 Word usage
The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shall equals is required to).
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required (should equals is reconzinended that).
The word may is used to indicate a course of action permissible within the limits of the standard (may equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to).

For the purposes of this document, the following terms and detinit ions apply. [he ILLE 3ianclards L)ictionarv Online should be consulted for terms not defined in this clause.
dry-band arcing: A surface discharge across a dry-band formed between liquid-contaminant electrodes.
electrowetting: The modification by the applied electric field of the wetting properties of a surface that is typically hydrophobic.
erosion: Loss of material from the insulation surface as impinged by dry-band arcing heat during the inclined plane tracking and erosion test.
inclined plane tracking and erosion test: A laboratory inclined-plane liquid-contaminant test introduced by Mathes and McGowan to evaluate the tracking and erosion resistance of high voltage outdoor insulating materials.
