Stray Currents Beyond the Fundamental in the Swedish BT Railway Power System
EnergiesSweden has a very high and variable soil resistivity, making it difficult to ensure a consistently good connection to earth along the track. Booster Transformers (BTs) have been used to ensure that the current returns through the intended path and that ...

The Effect of Soil Type on Touch Voltage and Step Voltage in the Grid Grounding System
ELKHAThe grounding system is one of the security systems in substations to channel excess voltage caused by lightning strikes that occur at substations, as well as electrical equipment. To design a grounding system, there are several factors that must be considered, including the type of soil, the configuration of the grounding system, the resistivity of ...
