IEC TS 63042-201:2018(E), which is a Technical Specification, provides common rules for the design of substations with the highest voltages of AC transmission systems exceeding 800 kV, so as to provide safety and proper functioning for the intended use.

This part of IEC 60099 provides information, guidance, and recommendations for the
selection and application of surge arresters to be used in three-phase systems with nominal
voltages above 1 kV. It applies to gapless metal-oxide surge arresters as defined in
IEC 60099-4, to surge arresters containing both series and parallel gapped structure – rated
52 kV and less as defined in IEC 60099-6 and metal-oxide surge arresters with external series
gap for overhead transmission and distribution l...view more

This part of IEC 61643 covers the application of surge isolation transformers (SITs) that are
used in telecommunication transformer applications with signal levels up to 400 V peak to
peak. These transformers have a high rated impulse voltage with or without screen between
the input and output windings. SITs are components for surge protection and are used to
mitigate the onward propagation of common-mode voltage surges. This document describes
SITs' selection, application principles and re...view more

To add an annex for portable SPDs for household and similar use.
This annex will contain the following specific requirements to ensure the requested level of intrinsic safety for such products, i.e. product tests and safety cannot rely on any external means:
- The position of the disconnector(s) : internal, i.e. all tests shall be made and passed without the help of any external means,
- Additional specifications for tests taking into account that line and neutral terminals can be reversed,

This part of IEC 60099 covers metal-oxide surge arresters with external series gap (externally
gapped line arresters (EGLA)) that are applied on overhead transmission and distribution
lines, only to protect insulator assemblies from lightning-caused flashovers.
This document defines surge arresters to protect the insulator assembly from lightning-caused
over-voltages only. Therefore, and since metal-oxide resistors are not permanently connected
to the line, the following items are not consi...view more
