INTERNATIONAL ELECTROTECHNICAL COMMISSION
TERMINAL AND TAPPING MARKINGS
FOR POWER TRANSFORMERS
FOREWORD
I) The formal decisions or agreements of the I EC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
ational unification, the I EC expresses the wish that all National Committees should adopt
3) In order to promote intern
the text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence
between the I EC recommendations and the corresponding national rules should, as far as possible, be clearly indicated
in the latter.
PREFACE
C Technical Committee No. 14, Power Transformers.
This report has been prepared by I E
A first draft was discussed at the meeting held in Athens in 1972, as a result of which, a draft, Docu-
ment 14(Central Office)26, was submitted to the National Committees for approval under the Six Months'
Rule in January 1974. In view of the number of basic comments on Document 14(Central Office)26, it
was referred back to Technical Committee No. 14 for further consideration, and this took place at the
meeting held in Helsinki in 1977. At this meeting, it was agreed that the document should be published
for guidance, rather than as a mandatory standard, and it is therefore published as a report.
The following countries voted explicitly in favour of publication:
Argentina Netherlands
Austria Norway
Belgium Poland
Romania
Czechoslovakia
South Africa (Republic of)
Denmark
Spain
Finland
Switzerland
Germany
Turkey
Hungary
Union of Soviet Socialist Republics
Israel
United States of America
Italy
Japan Yugoslavia
The Australian National Committee voted against publication of document 14(Central Office)26,
because it considers the numbering system should be in numerical order throughout the winding. Fur-
thermore, the use of the letters U, V and W is not favoured.

TERMINAL AND TAPPING MARKINGS
FOR POWER TRANSFORMERS
1. Scope
This report gives guidance on markings for the terminals and tappings of power transformers in
accordance with the rules given by I E C Technical Committee No. 16 for a uniform alphanumeric
system of terminal markings *.
Only simple examples are illustrated, more complicated cases, e.g. two units in one tank, being
subject to agreement between the manufacturer and the purchaser.

identification may be omitted. Should numerical character groups having different significance be
