27、voltage ratio and impedances of traction converter transformers.20 Introduction HD 591 S1 was prepared jointly by SC 9XC and TC 14 to face specific aspects of the transformers used in fixed installations of traction systems, which differ from other transformers. In effect transformer standards are m
28、ainly dealing with three-phase transformers or single-phase units assembled to a three-phase bank. Application of such standards to single- or bi-phase transformers as used in traction systems is not evident. Moreover, EN 61378-1 deals with converter transformers for industrial use which have loadin
29、g characteristics different from traction transformers for converters. Therefore HD 591 S1 and this document were set up to clarify such particular aspects. HD 591 S1 was studied in early 90 and published in 1993 and experienced during the period 1993 to 1997. Then, having decided to convert the HD
30、into an EN, the opportunity was taken to revise the document to introduce the improvements that have been found suitable during this trial period. BS EN 50329:2003+A1:2010EN 50329:2003+A1:2010 (E) 4 1 General 1.1 Scope This European Standard covers specific characteristics of traction transformers a
31、s defined in 1.3.1, used in traction substation or along the track for the supply of power to a.c. and d.c. traction systems or to provide power to auxiliary services. Traction transformers are either - single-phase traction transformers, - single-, three- or poly-phase rectifier-transformers or con
32、verter/inverter-transformers for d.c. or a.c. contact line, - single phase auto-transformers for traction power supply, - single- or three-phase auxiliary transformers at traction supply voltage. Transformers feeding a.c. contact lines are covered by EN 60076. Dry-type transformers are covered by HD
33、 464. These standards are valid with the additional requirements given in this document. For transformers feeding contact lines through static converters EN 61378-1 may assist, but modified or additional requirements are given in this document. NOTE Transformers mounted on-board traction vehicles ar
34、e covered by EN 60310 and are excluded from the scope of this document. Electromagnetic compatibility is ruled by EN 60076-1 which states that a transformer may be considered a passive element in this respect. Some accessories however are subject to EMC requirements and shall comply with EN 50121-5.

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or re
