EN 50329:2003

Railway applications - Fixed installations - Traction transformers

This European Standard covers specific characteristics of traction transformers as 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 converter/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 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 are 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.

Overview

EN 50329:2003 - "Railway applications - Fixed installations - Traction transformers" is a European Standard published by CLC that defines the specific characteristics and additional requirements for traction transformers used in railway fixed installations. It covers traction transformers installed in traction substations or along the track for supplying power to a.c. and d.c. traction systems and for powering auxiliary services. The standard specifies the scope of equipment covered and clarifies exclusions (for example, onboard transformers are excluded and covered by EN 60310).

Key topics and requirements

EN 50329:2003 focuses on the particular needs of railway traction transformers rather than general-purpose distribution transformers. Covered transformer types include:

• Single-phase traction transformers
• Single-, three- or poly-phase rectifier-transformers
• Converter/inverter-transformers for d.c. or a.c. contact lines
• Single-phase auto-transformers for traction power supply
• Single- or three-phase auxiliary transformers at traction supply voltage

Key technical topics addressed (in scope or as additional requirements) include:

• Specific electrical characteristics required for traction service and interaction with converters/rectifiers
• Additional requirements beyond general transformer standards for safe and reliable railway operation
• Interfaces with static converters and power electronics (reference to EN 61378-1 as an aid, with modified requirements in EN 50329)
• Electromagnetic compatibility (EMC) considerations - transformers are generally passive per EN 60076-1, but some accessories must comply with EMC requirements in EN 50121-5
• Relationship to other transformer standards - e.g., transformers feeding a.c. contact lines conform to EN 60076 and dry-type transformers are covered by HD 464, with EN 50329 providing railway-specific additions

Applications

EN 50329 is intended for use where traction transformers are part of fixed railway infrastructure:

• Traction substations supplying overhead contact lines or third-rail systems
• Trackside installations and auxiliary power supply for stations and signaling
• Projects involving rectifier or inverter stations where transformer-to-converter interaction is critical

Who uses this standard

• Railway electrical engineers and system designers
• Transformer manufacturers and suppliers targeting the rail market
• Procurement teams and specification writers for rail projects
• Test laboratories and conformity assessment bodies
• Maintenance and safety engineers overseeing fixed traction installations

Related standards

• EN 60076 (power transformers)
• HD 464 (dry-type transformers)
• EN 61378-1 (transformers for static converters) - informative assistance
• EN 60310 (onboard traction transformers) - exclusion
• EN 60076-1 (EMC considerations)
• EN 50121-5 (EMC requirements for accessories)

Keywords: EN 50329:2003, traction transformer, railway applications, traction substation, rectifier-transformer, converter-transformer, EMC, traction power supply.
