The fault protection device includes a controller adapted to monitor the spur current, and isolation means to fully or partially isolate the spur from the trunk upon receiving of an activation signal from controller. The controller comprises a failure status determination algorithm comprising an intermittent fault count over time step and a fault duration step. The intermittent fault count step is satisfied if a pre-determined number of separate faults are detected over a first time period. The fault duration step is satisfied if a fault is detected which persists for longer than a second time period. The controller issues the activation signal upon determination of a failure status on the spur which satisfies the intermittent fault count and/or the fault duration step of the algorithm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Two wire combined power and data network system segment with fault protection device","description":"A segment of a two wire combined power and data network for automation has a trunk, a spur mounted thereon and a fault protection device.
