Power distribution automation system with fiber-enabled fail-over protection
A recently granted patent (Publication Number: US11889244B2) discloses a method and apparatus for fault management in optical communication networks. The method involves determining faults in a first communication path with linear protection, transferring the connection to a second path, and transferring power supply accordingly. The end point, which can be an electrical power recloser, is prompted to switch power supply within 15 milliseconds of detecting the fault. The fault determination can be based on continuity check messages or signals from Multi-Chassis Link Aggregation protocols.
Additionally, the apparatus described in the patent includes processors and memory storing instructions for fault management in optical communication networks. It determines faults, transfers connections, and manages power supply transfers between communication paths. The apparatus is also capable of sending notifications indicating the fault location, potential cause, and estimated repair time. This technology is crucial for maintaining seamless communication in optical networks, ensuring quick fault detection, and minimizing downtime by swiftly transferring connections and power supplies to alternate paths.
