WebFeb 24, 2012 · The differential relay is one that operates when there is a difference between two or more similar electrical quantities exceeds a predetermined value. In the differential relay scheme circuit, there are two currents come from two parts of an electrical power circuit. These two currents meet at a junction point where a relay coil is connected. WebApr 22, 2014 · Solkor RF. The N model can handle a variety of pilot interfaces, including RS485, RS232, and fiber-optic: Solkor N. My preference would be fiber-optic. The interfacing with the relay is simpler (just plug it in). The 5kV pilot wire needs to be converted properly to bring it safely down to device-level voltages, which means extra equipment.
