IEC TS 63414:2025(Main)

Artificial pollution tests on high-voltage polymeric insulators to be used on AC and DC systems

IEC TS 63414:2025 is applicable for the determination of the AC and DC pollution flashover and withstand voltage characteristics of insulators with polymeric housing, to be used outdoors in HV applications and exposed to polluted environments. This is also applicable for insulators with hydrophobic coatings. This document refers to AC systems with a rated voltage greater than 1 000 V and DC systems with a rated voltage greater than 1 500 V.
The object of this technical specification is to prescribe standardized test methods, requirements and procedures for artificial pollution tests applicable to polymeric insulators for overhead lines including traction lines, station post and hollow insulators of equipment. Available test experience with polymeric station post and hollow insulators, especially for DC applications, is limited.
The proposed tests are not applicable to ceramic and glass insulators without polymeric housing, to greased insulators or to special types of insulators (e.g., insulators with semiconducting glaze).
Differently to ceramic and glass insulators without polymeric housing:
- The pollution performance of insulators with polymeric housing varies with the hydrophobicity condition of the surface. The specific conditions simulated by standardized tests might not represent the actual dynamic field conditions.
- The determination of the flashover and/or withstand voltage under pollution conditions is not enough for dimensioning. Additional constraints related to possible ageing are also to be considered.
- If the Hydrophobicity Transfer Material (HTM) test according to IEC TR 62039 confirms that an insulator is non-HTM, it can be tested according to IEC 60507 or IEC TS 61245.

IEC TS 60815-1:2025(Main)

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 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. The term "insulator" is used hereafter to refer to any type of insulator.
The objective of this technical specification series is to:
- understand and identify parameters of the system, application, equipment and site influencing the pollution behaviour of insulators,
- understand and choose the appropriate approach to the design and selection of the insulator solution, based on available data, time and resources.
- characterise the type of pollution at a site and determine the site pollution severity (SPS) value and the SPS class,
- determine the reference unified specific creepage distance (RUSCD) of "reference" insulator based on the SPS class,
- select candidate insulators and determine corrections to apply to RUSCD to arrive at the USCD of the "candidate" insulators by taking into account their specific properties (notably their shed profiles), conditions of the site, the application and the type of system,
- evaluate the relative advantages and disadvantages of the possible solutions, using HTM or non-HTM insulators,
- assess the need and merits of "hybrid" solutions or mitigative measures.
The IEC 60815 series does not deal with the effects of ice and snow on polluted insulators.
CIGRE documents form a useful complement to this technical specification for those wishing to study in greater depth the performance of insulators under pollution.
This second edition cancels and replaces the first edition of IEC TS 60815‑1 published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) In the Scope, it is clarified that this specification is applicable to AC and DC conditions while it mainly refers to AC conditions. Detailed application indications refer to AC only. The RUSCD is determined based on the SPS class of reference insulators, and this document does not deal with the effects of ice and snow on polluted insulators;
b) Some terms and definitions are modified or introduced in this document, such as RUSCD, creepage factor, average diameter, SPS value and SPS class, hydrophobicity transfer and HTM, etc.;
c) Clause 5 is re-organized and revised regarding input parameters for the selection and dimensioning of insulators, including system requirements and environmental conditions;
d) Clause 6 "Determination of site pollution severity (SPS) class" is re-organized and re-written. A distinction was made between SPS value and SPS class. The measurement of pollution that is made on the de-energized reference insulator is valid for AC only;
e) A new pollution class, extremely heavy class f, is added. It is applicable only to the special situations of extremely heavy pollution when the RUSCD of class e cannot meet the requirements. The RUSCD value for class f is not specified;
f) The parameters of reference insulators were defined;
g) The pro

Polymeric HV insulators for indoor and outdoor use - General definitions, test methods and acceptance criteria

IEC 62217:2025 is applicable to polymeric insulators for AC systems with a nominal voltage greater than 1 000 V (frequency less than 100 Hz) and DC systems with a nominal voltage greater than 1 500 V whose insulating body consists of one or various organic materials. Polymeric insulators covered by this document are intended for use both on HV overhead lines and in substations, in both indoor and outdoor applications. They include composite insulators with solid and hollow core and resin insulators. Hybrid insulators with ceramic core and polymeric housing are also included, while coated insulators (e.g. with RTV silicone rubber coatings) are not included in this standard. Electrical tests described in this document are done under AC voltage and are in general applicable to insulators to be used in DC systems too. Tests under DC voltage are intended to reflect up-to-date knowledge and experience. Only polymeric housing materials of hybrid insulators are specified in this document. Tests for core materials and the interfaces between housing and core of hybrid insulators are not included.
The object of this document is
- to define the common terms used for polymeric insulators;
- to prescribe common test methods for design tests on polymeric insulators;
- to prescribe acceptance or failure criteria, if applicable;
These tests, criteria and recommendations are intended to ensure a satisfactory lifetime under normal operating and environmental conditions. This document includes design tests intended to reject materials or designs which are inadequate under normal operating and environmental conditions. This document defines test methods and acceptance criteria. The applicable tests are given in the relevant product standard. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The scope of the document is specified to comprise composite insulators with solid and hollow core and resin insulators used for both AC and DC systems in indoor and outdoor applications of HV overhead lines and substations; hybrid insulators (defined in IEC TS 62896) with ceramic core and polymeric housing are also included, while coated insulators (e.g. with Room Temperature Vulcanized (RTV) silicone rubber coatings) are not considered in this document;
b) Steep-front impulse voltage test is modified to avoid unwanted flashovers between the leads of the electrodes;
c) Differences between hydrophobicity transfer material (HTM) and non-HTM housing materials are specified and relevant test methods and acceptance criteria for polymeric insulators with HTM housing are introduced;
d) The previous water diffusion test on core materials with or without housing is split into two tests. One is on core materials without housing, the other is on core materials with housing. The acceptance criteria are modified;
e) Stress corrosion test for core materials is introduced;
f) Annex B summarizes the test application for evaluating the quality of interfaces and connections of end fittings, housing materials and core materials;
g) Annex E is introduced to emphasize the need for control of electric fields of polymeric insulators for AC. The control of electric fields of polymeric insulators for DC is still under consideration.
