NEN-EN-IEC 61377 applies to the traction system consisting (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, contactors, etc. Figure 1 is just an overview and is not representative of all traction system architectures. Current collector, mechanical braking systems and gearbox are not in the scope of this standard. Types of motors applicable in this standard are asynchronous, or synchronous including permanent magnet (PMM), or direct current (DC). The auxiliary converter(s) is (are) part of the scope 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.
