Discussion on DC and AC Power Quality Assessment in Railway Traction Supply Systems [PDF]
The assessment of the power quality could be a valuable tool to foster the efficiency of the whole railway system by “awarding” the good power quality delivered and absorbed. Power quality is a well-addressed topic in conventional AC 50/60 Hz power systems and many procedures, algorithms and measurement systems were presented in international standards
