Selection and dimensioning of high-voltage insulators intended for use in polluted conditions - Part 1: Definitions, information and general principles (IEC TS 60815-1:2025)
Abstract
This document, which is a technical specification, is applicable to the selection of insulators, and the determination of their relevant dimensions, to be used in outdoor high-voltage systems with respect to pollution. For the purposes of this technical specification series, the insulators are divided into the following broad categories, each dealt with in a specific part as follows: – IEC TS 60815-2 – Ceramic and glass insulators for AC systems; – IEC TS 60815-3 – Polymer insulators for AC systems; – IEC TS 60815-4 – Insulators for DC systems. This document provides general definitions, gives methods for the evaluation of site pollution severity (SPS) and outlines the principles to arrive at an informed judgement on the probable behaviour of a given insulator in certain pollution environments. The general principles described are applicable to both AC and DC systems. However, the applicability part mainly refers to AC. More information about DC can be found in IEC TS 60815-4. This document is applicable to all types of external insulation, including insulation forming part of other apparatus.
