Abstract
A power distribution and communication system includes nodes connected by power lines and communication links. The system receives power from one or more power sources. Each node contains at least one power port, data port and load port. Associated with each power port and load port is a port monitor for measuring current flowing into or out of the port and the voltage difference between the port outlet and ground, which measurements are passed to a processing element. The processing element and monitor analyze measured values to detect fault conditions. Upon fault condition detection, the port is disabled by opening a switch, disconnecting the port from the system voltage. The processing element receives power directly from the power line, thus receiving power from a live power line even if the associated power port is disabled allowing the processing element to enable a disabled node following a failure.
