IVNI - High voltage power installations
To prepare harmonized standards for high voltage power installations (exceeding 1 kV a.c. or 1.5 kV d.c.) located indoors or outdoors, including earthing. The standards will specify the design requirements of the installations and the selection and erection of electrical equipment in order to ensure the safety of persons and the proper operation of the installations.
Visokonapetostne inštalacije
Standardizacija inštalacij na področju napetosti, ki presegajo 1 kV izmenične napetosti oziroma 1,5 kV enosmerne napetosti v zaprtih in odprtih prostorih, vključno z ozemljitvijo. Standardi specificirajo projektne zahteve inštalacij, izbiro in izvedbo električne opreme za zagotovitev varnosti ljudi in pravilnega delovanja in se nanašajo na tovarniško izdelano in tipsko preskušeno opremo ter njeno pravilno inštaliranje.
General Information
This part of IEC 60071 applies to three-phase AC 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 are selected.
This document describes that the selected withstand voltages are 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 document.
Although the principles of this document also apply to transmission line insulation, the values
of their withstand voltages can be different from the standard rated withstand voltages.
The apparatus committees are responsible for specifying the rated withstand voltages and the
test procedures suitable for the relevant equipment taking into consideration the
recommendations of this document.
NOTE In IEC 60071-2, all rules for insulation co-ordination given in this document are justified in detail, in
particular the association of the standard rated withstand voltages with the highest voltage for equipment. When
more than one set of standard rated withstand voltages is associated with the same highest voltage for equipment,
guidance is provided for the selection of the most suitable set.
This horizontal standard is primarily intended for use by technical committees in the
preparation of standards in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
horizontal standards in the preparation of its publications. The contents of this horizontal
standard will not apply unless specifically referred to or included in the relevant publications.

This part of IEC 61936 provides common rules for the design and the erection of electrical power installations in systems with nominal voltages above 1 kV a.c. and nominal frequency up to and including 60 Hz, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this standard, an electrical power installation is considered to be one of the following:
a) Substation, including substation for railway power supply
b) Electrical installations on mast, pole and tower
Switchgear and/or transformers located outside a closed electrical operating area
c) One (or more) power station(s) located on a single site
The installation includes generators and transformers with all associated switchgear and all electrical auxiliary systems. Connections between generating stations located on different sites are excluded.
d) The electrical system of a factory, industrial plant or other industrial, agricultural,
commercial or public premises
The electrical power installation includes, among others, the following equipment:
– rotating electrical machines;
– switchgear;
– transformers and reactors;
– converters;
– cables;
– wiring systems;
– batteries;
– capacitors;
– earthing systems;
– buildings and fences which are part of a closed electrical operating area;
– associated protection, control and auxiliary systems;
– large air core reactor.
NOTE In general, a standard for an item of equipment takes precedence over this standard. This standard does not apply to the design and erection of any of the following:
– overhead and underground lines between separate installations;
– electric railways;
– mining equipment and installations;
– fluorescent lamp installations;
– installations on ships and off-shore installations;
– electrostatic equipment (e.g. electrostatic precipitators, spray-painting units);
– test sites;
– medical equipment, e.g. medical X-ray equipment.
This standard does not apply to the design of factory-built, type-tested switchgear for which separate IEC standards exist. This standard does not apply to the requirements for carrying out live working on electrical installations. If not otherwise required in this standard, for low-voltage electrical installations the standard series IEC 60364 applies.
