Abstract
An electric power distribution system is shown where even if supply of electric power is interrupted, other normal electric part systems can be operated. A number of electric power distribution portions are supplied with electric power through at least two systems of electric power lines. The amounts of electric currents in the two systems of the trunk lines respectively are detected and monitored by a sensor and each current detection portion. Moreover, a controller controls a switch corresponding to a sensor which has detected an abnormal value among output values from a number of current detection portions to make non-conductive the trunk line from which the abnormal value has been detected. If a fault takes place in, for example, the trunk line between the electric power distribution portions, the two ends of the trunk line respectively are disconnected by the switch. Moreover, electric power is supplied from another electric power distribution portion through the residual electric power line of the two systems of the electric power lines.
