Home / Fiber Optic Cable Differential Protection
Differential protection is based on Kirchhoff's laws, stating that all current into a network node shall add up to 0 in an ideal system. RED615 is a phase-segregated, two-end, line differential protection and control relay for protection, control, measurement and supervision of overhead line and cable feeders in utility and industrial power distribution networks, including radial, looped and meshed distribution networks, with or. This paper intends to briefly compare the protection of buried three phase high voltage cable with Solkordifferential protection relay using metallic pilot wires orfibre optic pilot wires. Dielectric property of the fiber optic provides complete electrical isolation as well as interference free.
