| Abstract |
The power outage of the Kyung-Won railway in February 2024 in South Korea sheds light on opening a new realm of research, where experiments, detailed modelling, and the theories of Nikola Tesla and Sebastian Z. Ferranti came into play. Consecutive panel discussions concluded that a single reason could not explain the destruction of the light arrester at the Yeon-Cheon Sub Sectioning Post (SSP) on the railway, only to know that the ferro resonance at the transformer at the SSP, whose causes are difficult to identify, damaged the light arrester. Since the harmonic wave frequencies, having led to high voltage at the transformer, are baseless according to general theories, the discussion opens the door to investigating energy augmentation at the end of the energy supply facility with a more concrete modelling of long-distance power supply systems, experiments based on the two scientists’ theories. |
