prBAS IEC TS 60071-4:2027

IEC TS 60071-4:2026, which is a technical specification, gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendations:<br /> • for the computational modelling of electrical systems, and<br /> • for the implementation of deterministic and probabilistic methods adapted to the use of numerical programmes.<br /> 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.<br /> This edition cancels and replaces IEC TR 60071-4, published in 2004. This edition constitutes a technical revision.
