Abstract: In the railway field, an energy-saving project is underway through the use of superconducting technology. Superconducting materials are expected to be effectively applied in a variety of fields such as power transmission with zero resistance, magnetic fields, etc. By using superconducting materials to develop cables for railway power transmission, it is possible to increase regeneration efficiency, reduce power loss, smooth the load between substations and intensify the substations through containment of voltage drop. By using a newly developed superconducting feeder system, we verified a power transmission. We conducted a train running by using actual trains on a DC 1500 V trolley system. While conducting the transmission, we specifically analyzed the energy generated when a cable was adopted into the railway line. As a result of adoption of a superconducting cable, the energy-saving rate increased as its length was extended. With a short cable, we found out that the voltage drop specific to railways could be reduced.
