The degree of danger for the victim is a function of the magnitude of the current, the parts idc the body through which the current passes, and the duration of current flow. When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the current is not interrupted in a very short time.

Connection to the LV utility distribution network.

Contact with parts in fault conditions Indirect contact. The relationship between current and voltage is not linear because the impedance of the human body varies with the touch voltage, and data on this relationship is therefore required.
