UNE-EN 61377:2016

This IEC 61377 standard applies to the traction system consisting (when it applies) of traction motor(s), converter(s), traction control equipment including software, transformer, input filter, brake resistor, main circuit-breaker, cooling equipment, transducers, contactors, etc.

Pantograph, mechanical braking systems and gear box are not in the scope of this standard.

The types of motors applicable in this standard are asynchronous motors, or synchronous motors including permanent magnet motors (PMM), or direct current (d.c.) motors.

The auxiliary converter is part of the scope when the auxiliary converter is enclosed within the traction converter. Otherwise, when the traction system is feeding an auxiliary system outside the traction converter, the auxiliary system can be replaced by an equivalent load.

NOTE 1: Energy storage system is not considered yet in this standard since there is no specific type test standard for energy storage system.

NOTE 2: Auxiliary loads validation is not part of this standard.

NOTE 3: The gear box can be part of test set-up but it is not a part of traction system under test.

The scheme of Figure 1 is just an example and is not representative of all traction system architectures.

The objective of this standard is to specify the type test of traction system, mainly comprising:

test of performance characteristics;

test methods of verifying these performance characteristics.

This standard does not specify the type test of each individual component.

The traction system under test incorporates at least one complete traction conversion line (at least one traction converter and its related loads, one transformer in case of a.c. supply or input filter in case of d.c. supply). The representativeness of the traction system under test versus the traction system is agreed between user and manufacturer during the tender phase.

The traction system under test is equipped with components that are representatives of the series production. Deviations may be allowed by agreement between user and manufacturer, and are justified from an impact stand point in advance of the test. Using equivalent components or parts are allowed if no significant influence on the test result is expected.
