Safety of power transformers, power supplies, reactors and similar products -- Part 2-2: Particular requirements and tests for control transformers and power supplies incorporating control transformers
This part of IEC 61558 deals with safety aspects of control transformers and power supplies incorporating control transformers such as electrical, thermal and mechanical safety. This Part 2-2 is applicable to control transformers and power supplies incorporating both control transformers and electronic circuits. This Part 2-2 is not applicable to external circuits and their components intended to be connected to the input terminals, output terminals or socket-outlets of the transformer and power supplies. This Part 2-2 does not apply to transformers covered by IEC 60076-11. This Part 2-2 applies to stationary or portable, single-phase or poly-phase, air-cooled (natural or forced), independent or associated control transformers and power supplies incorporating a control transformer, having a rated supply voltage not exceeding 1 000 V a.c. and rated supply and internal operating frequency not exceeding 500 Hz. The rated thermal output does not exceed: - 25 kVA for single-phase control transformers and power supplies incorporating control transformers; - 40 kVA for poly-phase control transformers and power supplies incorporating control transformers. This Part 2-2 is applicable to control transformers and power supplies incorporating control transformers without limitation of the rated output subject to an agreement between the purchaser and the manufacturer. This Part 2-2 is applicable to dry-type transformers. The windings may be encapsulated or non-encapsulated. The no-load output voltage or the rated output voltage does not exceed 1 000 V a.c. or 1 415 V ripple-free d.c. For independent control transformers and independent power supplies incorporating control transformers, the no-load output voltage and / or the rated output voltage is not less than 50 V a.c., or 120 V ripple free d.c.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International standard IEC 61558-2-1 has been prepared by IEC technical committee 96: Small power transformers, reactors, power supply units and similar products. This second edition cancels and replaces the first edition published in 1997. It constitutes a technical revision. The main changes consist of updating this Part 2-2 in accordance with Part 1, edition 2, and adding power supplies to the scope. This Part 2-2 has the status of a group safety publication in accordance with IEC Guide 104: The preparation of safety publications and the use of basic safety publications and group safety publications (1997).

SAFETY OF POWER TRANSFORMERS, POWER SUPPLIES,
REACTORS AND SIMILAR PRODUCTS
Part 2-2: Particular requirements for control transformers and power
supplies incorporating control transformers
1 Scope
Replacement:
This International standard deals with safety aspects such as electrical, thermal and
mechanical safety of control transformers and power supplies incorporating control
transformers.
This standard is applicable to transformers and power supplies incorporating electronic circuits.
This standard is not applicable to external circuits and their components intended to be
connected to the input and output terminals or socket- outlets of the transformer and power
supplies
This part 2-2 of IEC 61558 applies to stationary or portable, single-phase or poly-phases, air-
cooled (natural or forced), independent or associated control transformers and power
supplies incorporating control transformer, having a rated supply voltage not exceeding 1
000 V a.c. and rated supply and internal operating frequency not exceeding 500 Hz.
The rated output does not exceed:
-25 kVA for single-phase control transformers; and power supplies incorporating
control transformer
-40 kVA for poly-phase control transformers; and power supplies incorporating control
transformer
This standard is also applicable to control transformers and power supplies incorporating
control transformer without limitation of the rated output subject to an agreement between
the purchaser and the supplier.
This standard is applicable to dry-type transformers. The windings may be encapsulated or
non-encapsulated.
The no-load output voltage and the rated output voltage do not exceed 1 000 V a.c. or
1 415 V ripple free d.c.
For independent control transformers the no-load output voltage is not less than 50 V a.c.,
Small power transformers, reactors, power suppl units and similar products and for
independent power supplies incorporating control transformer the no load output voltage not
less than 50 V a.c or 120 V ripple free d.c.
Transformers covered by this standard are used only in applications where double or
reinforced insulation between circuits is not required by the installation rules or by the
appliance specification.
NOTE 1 – Normally, the transformers are intended to be associated with the equipment to provide voltages
different from the supply voltage for the functional requirement of the equipment. T
