Power Quality Assessment in Railway Traction Supply Systems [PDF]

IEEE Transactions on Instrumentation and Measurement, 2020
The assessment of the power quality (PQ) could be a valuable tool to foster the efficiency of the railway systems. PQ is a well-addressed topic in conventional ac 50/60 Hz power systems, and many procedures, algorithms and measurement systems were presented in the international standards and widely discussed in the scientific literature.
