scope:

This International Standard applies to the traction systemconsisting (when it applies) of traction motor(s), converter(s),traction control equipment including software, transformer, inputfilters, brake resistors, main circuit-breaker, cooling equipment,transducers, contactors, etc. Figure 1 is just an overview and isnot representative of all traction system architectures. Currentcollector, mechanical braking systems and gearbox are not in thescope of this standard. Types of motors applicable in this standardare asynchronous, or synchronous including permanent magnet (PMM),or direct current (DC). The auxiliary converter(s) is (are) part ofthe scope when the auxiliary converter is enclosed within thetraction converter. Otherwise, when the traction system feeds anauxiliary system outside the traction converter, the auxiliarysystem can be replaced by an equivalent load. NOTE 1 Energy storagesystem is not considered in this standard since there is nospecific type test standard for energy storage system. NOTE 2Auxiliary loads validation is not part of this standard. NOTE 3 Thegearbox can be part of test set-up, but it is not a part oftraction system. The objective of this standard is to specify thetype test of a traction system, mainly comprising of: ? test ofperformance characteristics; ? test methods of verifying theseperformance characteristics. This standard does not specify thetype test of each individual component. The traction system undertest incorporates at least one complete traction conversion line(at least one traction converter and its related loads, onetransformer in the case of AC supply or input filter in the case ofDC supply). The representativeness of the traction system undertest versus the actual traction system is agreed between the userand manufacturer. Figure 2 gives one example of the relationshipbetween the traction system under test and the whole tractionsystem. The traction system under test is equipped with componentsthat are representative of the production series. Deviations may bepermitted by agreement between user and manufacturer, and arejustified from an impact stand point in advance of the test. Usingequivalent components or parts is permitted if no significantinfluence on the test result is expected.
