High-impedance bus differential relay. (Power and Reliability Products).(Brief Article)
High-impedance bus differential relay provides monitoring, control, and protection while its high-impedance differential elements provide fast tripping for in-zone faults and greater security during heavy through-faults and current transformer (CT) saturation. Costing less than a system of traditional single-phase, electromechanical bus protection relays, according to the manufacturer, the relay incorporates three-phase protection, ...
