Line Differential Protection and Control RED615 ANSI
Compact and versatile solution for utility and industrial power distribution systems. RED615 is a phase-segregated, two-end line differential protection and control relay for overhead line and cable feeders, including radial, looped, and meshed networks, with or without distributed generation. It is also ideal for line differential applications with an in-zone transformer. Communication between substations is via fiber-optic or galvanic pilot wire link
