Abstract
The disclosed power distribution system regulates the transfer of energy from a source 1 to a load 3. Source Controller 5 on the source side closes Disconnect Device 7 and monitors the transfer of a pulse or “packet” of energy to the load side. A Load Controller 9 on the load side communicates the amount of energy received at the load back to the source controller via Communication Link 11. If it is confirmed that the energy received on the load side corresponds to that sent by the source side, another energy packet is sent. If the energy received does not correspond with that sent by the source side, energy transfer is stopped, indicating a system fault or safety hazard. The energy content of a single packet is kept small, such that if it is not properly delivered, it can not cause damage to equipment or harm personnel.
