Continuous Overvoltages on A.C. Traction Systems
IEEE Transactions on Power Apparatus and Systems, 1983Methods of calculating a. c. traction system overvoltages caused by harmonic distortion in the locomotive current waveforms are described. A comparison is made between the results of an analogue simulation and measurements obtained during a site test.

IET Professional Development Course on Electric Traction Systems, 2006
The development of a cost-optimal traction system towards a specific set of customer requirements is a complex, iterative process with many pitfalls. The new European market situation, with business-oriented operators specifying only their basic performance requirements and no technical details, and with a multinational industry where components such ...
