CCMC - wrong standard reference to be corrected

This document is applicable to plug-in type bushings, according to EN 60137, 72,5 kV, rated currents
from 630 A up to 1 250 A and frequencies from 15 Hz up to 60 Hz for single or three-phase arrangements in electrical equipment like liquid filled transformers or gas insulated switchgear and controlgear. It complements and amends, if necessary, the relevant EN standards.
The application of such plug-in type bushings is derived from EN 50180 and EN 50181 but applied for higher voltages with desc...view more

This International Standard applies to outdoor and indoor bushings of any voltage used on DC
systems, of capacitance graded or gas insulated types for use as components of oil-filled
converter transformers and smoothing reactors, as well as air-to-air DC bushings. This
standard does not apply to the following:
• cable terminations (potheads);
• bushings for instrument transformers;
• bushings for test power supplies;
• bushings applied with gaseous insulation (other than air at atmospheri...view more

IEC TS 60079-46:2017 specifies requirements for the design, construction, assembly, testing, inspection, marking, documenting and assessment of equipment assemblies for use in explosive atmospheres under the responsibility of the manufacturer of the equipment assembly. The requirements of this document apply to individual items according to the IEC 60079 series or ISO 80079 series that comprise the assembly and that have individual certificates. These individual items are then integrated as part...view more

IEC 62041: 2017 is applicable to transformers, reactors and power supply units covered by the IEC 61558 series of standards. This document deals with the electromagnetic compatibility requirements for emission and immunity within the frequency range 0 Hz to 400 GHz. No tests need to be performed at frequencies where no requirements are specified.
This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision.

IEC TS 61463:2016(E), which is a Technical Specification, is applicable to alternating current and direct current bushings for highest voltages above 52 kV (or with resonance frequencies placed inside the seismic response spectrum), mounted on transformers, other apparatus or buildings. For bushings with highest voltages less than or equal to 52 kV (or with resonance frequencies placed outside from the seismic response spectrum), due to their characteristics, seismic qualification is not used as...view more

This European Standard is applicable to ceramic and resin insulated bushings having highest voltages above 1 kV up to 52 kV, rated currents from 250 A up to 3 150 A and frequencies from 15 Hz up to 60 Hz for insulating liquid filled transformers.
This European Standard establishes essential dimensions, to ensure interchangeability of bushings and to ensure adequate mounting and interchangeability of mating plug-in separable connectors of equivalent ratings.

This European Standard should be considered in factual context with EN 50180-1 only. Constructional details
for fastenings and their details are supplementing EN 50180-1. This information is of importance for utilities
concerning compatibility.
For a better understanding of additional information some dimension from EN 50180-1 are repeated in this
European Standard.
This European Standard was extended for fastenings of bushings for a highest voltage of 52 kV.

This European Standard should be considered in factual context with EN 50180-1 only. The dimensional
supplements are related to figures and tables of EN 50180-1. To enable a better understanding of additional
information some tables from EN 50180-1 are used and extended.
This European Standard may now be used also for bushings with a highest voltage of 52 kV. Figures for the
details of the components and the related tables are added according to the extended range of voltage.
