This International Standard is applicable to newly manufactured instrument transformers intended for applications where the nominal voltage is higher than 1 kV AC or 1,5 kV DC, with analogue or digital secondary signal for measuring, protection and control purposes, with rated frequencies from 15 Hz to 400 Hz, or for DC applications.

NOTE 1 A bushing type current transformer, although having no primary insulation level for itself is often placed on a system with a nominal voltage > 1 kV AC or 1,5 kV DC and therefore falls within the scope of this document. Example: CT placed around a HV bushing or a cable.

The general requirements for instrument transformers for applications in LV systems (nominal voltage ≤ 1 kV AC or ≤ 1,5 kV DC) are covered by the standard IEC 61869-201.

This part of IEC 61869 is a product family standard and covers general requirements only. For each type of instrument transformer, the product standard is composed by this document and the relevant specific product standard.

This part of IEC 61869 defines the errors both for analogue and digital secondary signal. The other characteristics of a digital interface for instrument transformer are standardised in IEC 61869-9 as an application of the horizontal standard IEC 61850 series, covering communication networks and systems for power utility automation.

This part of IEC 61869 considers bandwidth requirements. The accuracy requirements on harmonics and requirements for the anti-aliasing filter are given in the sub-clause 5.7.

In case of LPIT, the general block diagram of single-phase devices is given in Figure 1.

According to the technology, it is not always necessary that all parts described in Figure 1 are included in the instrument transformer.

This part of IEC 61969 contains design guidelines for outdoor enclosures for electrical and electronic equipment and is applicable over a wide field of mechanical, electromechanical and electronic equipment and its installation where a modular design is used.

The objectives of this document are:

to provide an overview of specifications for enclosures focused on requirements for outdoor applications for stationary use at non-weather protected locations, and

to achieve product integrity under outdoor conditions and to ease product selection for the sourcing of outdoor enclosures from different vendors.

These enclosures are considered to contain any equipment and provide protection for the outdoor installed facilities against unwanted environmental impacts. The installed equipment can be, but is not limited to, subracks or chassis according to IEC 60917 (all parts) or IEC 60297 (all parts). A typical outdoor enclosure is shown in Figure 1.

This document defines the structure of a standardized digital representation of an asset, called Asset Administration Shell. The Asset Administration Shell gives uniform access to information and services.

The purpose of the Asset Administration Shell is to enable two or more software applications to exchange information and to mutually use the information that has been exchanged in a trusted and secure way.

This document focusses on Asset Administration Shells representing assets of manufacturing enterprises including products produced by those enterprises and the full hierarchy of industrial equipment. It defines the related structures, information, and services.

The Asset Administration Shell applies to:

any type of industrial process (discrete manufacturing, continuous process, batch process, hybrid production);

any industrial sector applying industrial-process measurement, control and automation;

the entire life cycle of assets from idea to end of life treatment;

assets which are physical, digital, or intangible entities.

This part of IEC 61108 specifies the minimum performance requirements, methods of testing and required test results for IRNSS shipborne receiver equipment, based on IMO resolution MSC.449(99) which uses the signals from the Indian Regional Satellite System (IRNSS) in order to determine position.

It takes account of the general requirements given in IMO resolution A.694(17) and is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence. It also takes into account, as appropriate, requirements for the presentation of navigation-related information on shipborne navigational displays given in IMO resolution MSC.191(79) and is associated with IEC 62288.

This receiver standard applies to navigation in ocean waters for the standard positioning service and harbour entrances, harbour approaches and coastal waters, as defined in IMO resolution A.1046(27) within IRNSS/NavIC coverage area.

All text of this standard, whose meaning is identical to that in IMO resolution MSC 449(99), is printed in italics and the resolution and paragraph number indicated between brackets i.e. (M.449(99)/A1.2).

The requirements in Clause 4 are cross-referenced to the tests in Clause 5 and vice versa.
