Investigation on the Thermal Impact of Low-Order Harmonics on Railway Power Supply Transformers

This article evaluates the thermal impact of low-order harmonics on transformer loading capabilities in the Swedish electric railway power system (ERPS). Using real power quality (PQ) measurements and standard methodologies from IEC and IEEE, it estimates the hot-spot temperature (HST), top-oil temp...
