REMOTE POWER MANAGEMENT AND MONITORING SYSTEM FOR SOLID STATE CIRCUIT BREAKER CONTROL WITH MANUAL BYPASS
A power management and monitoring system for controlling an electrical device powered by a power supply is disclosed. The system may include a circuit breaker enclosure box structured to monitor and manage power to the electrical device via a centralized data bus and centralized power bus. The circuit breaker enclosure box may include at least a remotely actuated solid state electronic circuit breaker (ECB) that monitors and manages power to the electrical device and a switch connected to the ECB and capable or remotely bypassing the ECB. The system may also include a display and controller that can remotely monitor and control the electrical device by remotely actuating the ECB.
H02J 13/00 - Circuit arrangements for providing remote indication of network conditions, e.g. an instantaneous record of the open or closed condition of each circuitbreaker in the networkCircuit arrangements for providing remote control of switching means in a power distribution network, e.g. switching in and out of current consumers by using a pulse code signal carried by the network
