This part of IEC 61892 specifies additional characteristics for electrical installations in mobile units. lt applies to installations that depend on buoyancy, such as column-stabilized units (semi-submersible units), ship- or barge-type units as well as self-elevating units. It specifies additional characteristics for such units, used during transfer from one location to another and for dilling, […]

This part of IEC 61 892 contains provisions for electrical installations in mobile and fixed offshore units including pipeline, pumping or ‘pigging’ stations, compressor stations and exposed location single buoy moorings, used in the offshore petroleum industry for drilling,processing and storage purposes. This International Standard applies to all installations, whether permanent, temporary,transportable or hand-held, to

This part of IEC 61850, which is a Technical Specification, applies to power utility automation systems (PUAS). It defines the communication between intelligent electronic devices (IEDs) in the power utility automation system and the related system requirements. This document contains the glossary of specific terminology and definitions used in the context of Power Utility Automation

This part of IEC 61 557 defines special performance requirements for hand-held and hand-manipulated current clamps and sensors for measurement of leakage currents in electrical distribution systems up to 1 000 V a.c. and 1 500 V d.c., taking into account the influence of high external low-frequency magnetic fields and other influencing quantities. This standard

This part of IEC 61 557 specifies the requirements applicable to measuring equipment for testing the phase sequence in three-phase distribution systems. Indication of the phase sequence can be mechanical, visual and/or audible. This document does not apply to additional measurements for other quantities. It does not apply to monitoring relays. NOTE Common worldwide three-phase

This part of IEC 61 557 specifies the requirements applicable to measuring equipment for testing the effectiveness of protective measures of residual current devices (RCD) installed in TT, TN and IT systems. It is not the purpose of this document to verify the RCD according to their product standards. NOTE Applicable tripping tests for time

NOTE 1 Throughout this part, the abbreviation PSC-ASSEMBLY (see 3.1 .1 01 ) is used for a power switchgear and controlgear ASSEMBLY. This part of IEC 61 439 defines the specific requirements of power switchgear and controlgear assemblies ( PSC-ASSEMBLIES) as follows : – ASSEMBLIES for which the rated voltage does not exceed 1 000
