Abstract:
A feeding system feeds power from a power unit to a load via a feeding line and includes a protection device configured to operate by a current equal to or greater than a predetermined current; a monitoring unit configured to monitor whether an accident occurs in the feeding line; and a gate block unit configured to stop the feeding of the power of the power unit when the monitoring unit detects that an accident causing the protection device not to operate has occurred.
