IEC TS 60071-4 ED1

Instructions for simulation-based insulation coordination and modelling of electrical networks

General information

50.20     May 1, 2026

PRVDTS    Jun 26, 2026

IEC

TC 99

Technical Specification

29.080.30  

Scope

IEC TS 60071-4:2026, which is a technical specification, gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendations:
• for the computational modelling of electrical systems, and
• for the implementation of deterministic and probabilistic methods adapted to the use of numerical programmes.
Its objective is to give information in terms of methods, modelling and examples that support the application of the approaches presented in IEC 60071-2:2023, and for the selection of insulation levels of equipment or installations, as defined in IEC 60071-1:2019
