Frequently Asked Questions
MT 48 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 38/MT 48". This committee has published 1 standards.
MT 48 develops IEC standards in the area of Information technology. Currently, there are 1 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC 61869-1:2023 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 an analogue or a digital secondary signal for measuring, protection and control purposes, with rated frequencies from 15 Hz to 400 Hz, or for DC applications.
The general requirements for instrument transformers for applications in LV systems (nominal voltage = 1 kV AC or = 1,5 kV DC) are covered by 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 of this document and the relevant specific product standard.
This part of IEC 61869 contains the requirements for the limits of 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 IEC 61850 horizontal standard 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 specified in 5.7.
IEC 61869-1:2023 cancels and replaces the first edition published in 2007 and IEC 61869-6:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) merger with IEC 61869-6:2016;
b) new scope: equipment for HV applications with a nominal voltage ; 1 kV AC or 1,5 kV DC;
c) new classification of some special tests as type tests or routine test;
d) additional type tests, additional special tests and new clause for commissioning tests;
e) new annexes E, F, G and I.
