IEC/TR 60071-4 Ed. 1.0 en:2004, Insulation co-ordination - Part 4: Computational guide to insulation co-ordination and modelling of electrical networks

Gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendations - for the numerical modelling of electrical systems, and - for the implementation of deterministic and probabilistic methods adapted to the use of numerical programmes. Its object is to give information in terms of methods, modelling and examples, allowing for the application of the approaches presented in IEC 60071-2, and for the selection of insulation levels of equipment or installations, as defined in IEC 60071-1.
