Full title and description

St IEC 61377-2016 — Railway applications — Rolling stock — Combined test method for traction systems. This international standard specifies combined type-test methods and performance characteristics for complete traction systems used on rolling stock, covering traction motors, converters, traction control equipment (including software), transformers, input filters, brake resistors, main circuit-breakers, cooling equipment, transducers, contactors and associated apparatus.

Abstract

IEC 61377:2016 defines procedures to evaluate the performance and verify the characteristics of traction systems as an integrated assembly under standardized test conditions. It addresses test setup and bench architecture, cooling conditions, mechanical output and loss measurement methods, and a set of type-test performance verifications applicable to AC (inverter-fed asynchronous or synchronous including permanent-magnet) and DC motor traction drives. The edition consolidates and updates earlier partized documents into a single combined test-method standard.

Scope

IEC 61377:2016 applies to traction systems of railway rolling stock and specifies type-test methods to assess system-level performance characteristics and verify those characteristics by testing. The standard covers the whole traction drive assembly (motors, converters, control electronics and software, transformers, filters, resistors, breakers, cooling and measurement interfaces) and is written to be applicable to asynchronous, synchronous (including permanent-magnet) and DC motor types. It also defines test-bench architectures, environmental and cooling conditions, and several alternative methods for measuring mechanical output and electrical losses.

Key topics and requirements

• Definition of combined type-test procedures for complete traction systems (system-level approach rather than separate component-only tests).
• Performance characteristics to be measured: torque, speed, efficiency, temperature rise, current/voltage behaviors and harmonic interactions.
• Test-bench architecture and setup requirements, including instrumentation and interfaces for full-system tests.
• Cooling and environmental conditioning requirements during tests to ensure repeatability and representativeness.
• Methods for mechanical output measurement: summation of losses, comparison of power, and comparison of current methods.
• Specification of acceptable test conditions, safety and measurement uncertainty considerations for type testing.
• Applicability to various motor technologies (asynchronous, synchronous including PM motors, and DC motors) and to inverter-fed drives.

Typical use and users

Used by railway rolling stock manufacturers, traction-system integrators, electrical and traction test laboratories, certification bodies, procurement and specification engineers, and maintenance organisations to qualify traction systems, verify performance claims, and ensure interoperability and safety compliance during type approval and acceptance testing.

Related standards

This edition replaces earlier partized documents (for example IEC 61377-1:2006 and other earlier parts) and is referenced alongside other railway electrotechnical standards such as the IEC 60077 series (electrical equipment of rolling stock) and IEC 60349 (electric traction — rotating electrical machines). European adoption as EN 61377:2016 aligns the document with CENELEC members.

FAQ

Q: What is this standard?

A: IEC 61377:2016 is an international standard that specifies combined test methods and performance verification procedures for complete traction systems used in railway rolling stock.

Q: What does it cover?

A: It covers system-level type tests for traction drives — including motors, converters, control equipment, transformers, filters, resistors, breakers and cooling — and defines test setups, measurement methods and required performance characteristics to be verified during type testing.

Q: Who typically uses it?

A: Traction and rolling-stock manufacturers, test laboratories, certification bodies, specification and procurement teams, and maintenance organisations use the standard to validate and certify traction systems.

Q: Is it current or superseded?

A: The 2016 edition (Edition 2.0) is the current consolidated edition that superseded earlier part-based publications such as IEC 61377-1:2006; users should verify national adoption dates for any regional equivalents.
