Abstract

Examined various cases of human touch to emergency equipment in the mains voltage up to 1 kV at different types of grounding system TN. In analyzing the various cases derived the analytical contact voltage relations depending on various parameters of the electrical network. For different cases of human touch in the TN system are reviewed transitional processes.
