General Information
Frequently Asked Questions
MT 7 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 14/MT 7". This committee has published 41 standards.
MT 7 develops IEC standards in the area of Information technology. Currently, there are 41 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 61378-1:2011 deals with the specification, design and testing of power transformers and reactors which are intended for integration within semiconductor converter plants. The scope of this International Standard is limited to application of power converters of any power rating. Typical applications are:
- thyristor rectifiers for electrolysis;
- diode rectifiers for electrolysis;
- thyristor rectifiers for large drives;
- thyristor rectifiers for scrap melting furnaces, and
- diode rectifiers feeding inverters for variable speed drives. The standard also covers the regulating unit utilized in such application as step down regulating transformers or autotransformers. This edition includes the following significant technical changes with respect to the previous edition:
- addition of winding connections with phase displacement (30°);
- addition of transformers with more than one active part in the same tank;
- change of reference power definition;
- addition of regulating transformer feeding converter transformer;
- addition of considerations about current sharing and hot spot temperature in high current windings for various winding arrangements;
- addition of transductors used for d.c. voltage regulation together with diode rectifiers. The contents of the corrigendum of January 2012 have been included in this copy.
