What is BS EN 61377 - Combined test method for traction systems about?
BS EN 61377 is a European standard that discusses the combined test method for traction systems for railways to ensure the efficiency of the traction system.
BS EN 61377 applies to the traction system consisting of (when it applies) of traction motor(s), converter(s), traction control equipment including software, transformer, input filters, brake resistors, main circuit-breaker, cooling equipment, transducers, contractors, etc.
Types of motors that are applicable in BS EN 61377 are asynchronous, or synchronous including permanent magnet (PMM), or direct current (DC).
The auxiliary converter is part of BS EN 61377 when the auxiliary converter is enclosed within the traction converter. Otherwise, when the traction system feeds an auxiliary system outside the traction converter, the auxiliary system can be replaced by an equivalent load.
Note 1: Current collector, mechanical braking systems and gearbox are not in the scope of BS EN 61377.
Note 2: The energy storage system is not considered in BS EN 61377 since there is no specific type test standard for the energy storage system.
Note 3: Auxiliary loads validation is not part of BS EN 61377.
Note 4: The gearbox can be part of the test set-up, but it is not a part of the traction system.
Who is BS EN 61377 - Combined test method for traction systems for?
BS EN 61377 on the combined test method for traction systems for railways is useful for:
- Technical or maintenance staff for traction systems for railways
- Test centres
- Regulatory authorities
Why should you use BS EN 61377 - Combined test method for traction systems?
Traction system that provides traction torque, converting the input supply energy into mechanical energy in motoring and the mechanical energy into electrical or thermal energy in braking (if applicable), comprising of the entire conversion equipment located between the current collector (excluded) and the motor shaft(s) and including all associated auxiliary equipment needed to operate the system.
BS EN 61377 guideline assists you with general test requirements and conditions such as test setup, cooling during the test, mechanical output measurement, tolerances, measuring accuracy, and environmental conditions for a combined test method for traction systems for railways.
BS EN 61377 also provides test methods on torque characteristics, efficiency consumption, energy consumption test, temperature rise, system function, variation of line voltage, system protection, and fault management for a combined test method for traction systems for railways.
With compliance and obedience to BS EN 61377, you can meet minimum requirements for traction systems for railways and efficiently assess traction systems.
What’s changed since the last update?
BS EN 61377:2016 supersedes BS EN 61377-1:2006, BS EN 61377-2:2002 and BS EN 61377-3:2002, which are withdrawn. BS EN 61377:2016 has included updates as necessary to meet the current technical state of the art, to improve clarity and to create an edition that considers all types of motors part of a traction system compared to the previous editions.
