Insulation Coordination Standards60071-1Insulation co-ordination - Part 1: Definitions, principles and rulesThis part of IEC 60071 applies to three-phase a.c. systems having a highest voltage for equipment above 1 kV. It specifies the procedure for the selection of the rated withstand voltages for the phase-to-earth, phase-to-phase and longitudinal insulation of the equipment and the installations of these systems. It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected. This standard recommends that the selected withstand voltages should be associated with the highest voltage for equipment. This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this standard. (Preview)60071-2Insulation co-ordination - Part 2: Application guideThis standard gives guidance for the determination of the rated withstand voltages for ranges I and II of IEC 60071-1 and justifies the association of these rated values with the standardized highest voltages for equipment. It covers phase-to-phase, phase-to-earth and longitudinal insulation of three-phase systems with nominal voltages above 1kV (Preview)60071-4Insulation co-ordination - Part 4: Computational guide to insulation co-ordination and modeling of electrical networksThis technical report gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendationsfor the numerical modeling of electrical systems including arresters andfor the implementation of deterministic and probabilistic methods adapted to the use of numerical programs.Its object is to give information in terms of methods, modeling 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.
