ABB Line Voltage Differential Protection and Control RED615 IEC Numerical Relay

Line differential protection and control RED615 ANSI IEC Numerical relay

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 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 without distributed generation. RED615 is also ideal for line differential applications with an in-zone transformer. RED615 relays communicate between substations either over a fiber-optic link or a galvanic pilot wire connection.

Compact and versatile solution for utility and industrial power distribution systems with integration of protection, control, monitoring and supervision in one relay.
