САЖЕТАК / ABSTRACT:
The paper analyzes the conductive interference of the electrical substation grounding system on a residential building. The building is located within the protective zone of the electrical substation, which creates a risk of excessive conductive interference in the event of a ground fault in the substation. Conductive interference can produce dangerous potentials in the vicinity of the substation, potentially leading to the occurrence of high values of touch and step voltages around the building. Additionally, there is a risk of these potentials being transferred to the building and its low-voltage installation. The paper analyzes these effects and provides an assessment of the risk of exposure to touch and step voltages, as well as an evaluation of the risk for the installations within the building.
