Frequently Asked Questions
WG 27 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 2/WG 27". This committee has published 8 standards.
WG 27 develops IEC standards in the area of Information technology. Currently, there are 8 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 60034-15:2009 relates to a.c. machines incorporating form-wound stator coils and specifies the test procedures and voltages to be applied to the main and interturn insulation of sample coils. The changes of this new edition with respect to the previous one are as follows:
- clarification of the title,
- removal of the limitation on voltage,
- additional definitions,
- additional guidance.

IEC/TS 60034-18-42:2008 defines criteria for assessing the insulation system of stator/rotor windings of single or polyphase AC machines which are subjected to repetitive impulse voltages, such as pulse width modulation converters, and expected to withstand partial discharge activity during service. It specifies electrical qualification and acceptance tests on representative samples which verify fitness for operation with voltage-source converters.

Defines criteria for assessing the insulation system of stator/rotor windings which are subjected to pulse width modulation drives. Applies to stator/rotor windings of single or polyphase AC machines with insulation systems for converter operation. Describes qualification and type tests on representative samples or on complete machines which verify fitness for operation with voltage source converters.
