Protection Against Electric Shock and Fire Hazards

In electrical power systems, the fault usually involves arcing and burning for all the wiring exposed to mechanical damages and all other insulation stresses like: -mobile circuits, -no fixed branch circuits, -electric appliances cords, -extensions. In AC low voltage systems, the arcing-fault is a weak point of the branch circuits. The paper introduces a -protection, by grounding and automatic disconnection of the supply. It deals with a short summary analyzing the risk factors of electric shock and fire hazards. The authors suggest the -protection as complete protection allowed wiring the circuits, including particularly extension cords, with special power cables, protected by ordinary ground fault protective devices. Converting the line-to-line fault into a line to ground fault or into a mixed type is the goal of this special cable type Faults Ground-Forced Cable (FGFC). This protection will be suitable, in industrial, commercial and residential applications, particularly for special mobile equipment and for hazardous locations, as construction sites.
