Capacitor bank Voltage protection Automatic voltage regulation Line differential modernization. Main customer benefits • Compact and versatile solution for utility and industrial power distribution systems with integration of protection, control, monitoring and supervision in one relay • Wide application coverage – feeder, transformer, motor, line differential, voltage, capacitor bank as well as generator and interconnection protection and control • Extensive range of protection and control functionality, either with sensors or conventional instrument transformers • Withdrawable plug-in unit...

RELION® 615 SERIES PROTECTION AND CONTROL RELAYS • = Supported o = Optional add-on Application REF615 has been designed to be the main overcurrent and earth-fault protection for overhead lines and cable feeders, in either isolated neutral, resistance-earthed, compensated or effectively-earthed distribution networks, depending on the standard configuration. REF615 is available in twelve standard configurations. In addition to standard configuration N, also L now provides maximum functionality to allow fully flexible tailoring. The major difference is that L includes support for three combi-sensor...

• = Supported o = Optional add-on Application RED615 has been designed to be the main protection for overhead line and cable feeders, in either isolated neutral, resistance-earthed, compensated or effectively earthed distribution networks, depending on the standard configuration. RED615 is available in five standard configurations, one of which is a plain line differential protection with overcurrent backup protection two with added earth-fault protection functionality in particular, and another two further extended with directional overcurrent as well as phase-voltage and frequency-based protection....

RELION® 615 SERIES PROTECTION AND CONTROL RELAYS RET615 has been designed to protect power transformers, including step-up transformers, and power generator-transformer blocks in utility and industrial power distribution systems. Application RET615 has been designed to be the main protection for two-winding power transformers and power generator-transformer blocks. RET615 is available in eight standard configurations to match the most commonly employed power transformer vector groups, and to coordinate the applied transformer neutral earthing principle with the relevant earth-fault protection...

Application REU615 is available in two standard configurations. One has been exclusively designed for busbar under- and overvoltage supervision, load-shedding (disconnection) and restoration (reconnection) applications. It can also be used for over- and underfrequency protection of power generators and other AC equipment such as capacitor banks. In generator and motor applications, REU615 provides • = Supported o = Optional add-on Product highlights • Extensive range of protection and control functionality for busbar voltage supervision, load-shedding and restoration, including over- and underfrequency...

RELION® 615 SERIES PROTECTION AND CONTROL RELAYS Application REM615 has been designed to be the main protection for asynchronous motors and their drives in manufacturing and process industry. Typically, the motor relay is used with circuit-breaker and contactor-controlled MV motors and medium-sized and large contactor-controlled LV motors in a variety of drives. The drives include both continuously and intermittently operated asynchronous motor drives with varying load, such as pumps and conveyors, crushers and choppers, mixers and agitators, fans and aerators. REM615 is available in four standard...

Application REV615 has been designed to be the main protection for H-bridge, double Y and single Y-connected capacitor banks and feeder cables. Additionally, REV615 can be used to protect harmonic filter circuits when no significant harmonic component is higher than the 11th. REV615 is available in two standard configurations, both of which offer three-phase overload protection, current-based unbalance protection with compensation for natural unbalance, and current-based switching resonance protection for capacitor banks. The overload protection includes an integrated undercurrent function which...

RELION® 615 SERIES PROTECTION AND CONTROL RELAYS • = Supported o = Optional add-on Application REG615 has been designed to be the main protection for small synchronous generators, and offer full protection during start-up and normal run for both the generator and the prime mover. REG615 can also be used as backup protection for medium-sized generators in applications where an independent and redundant protection system is required. The main protection functionality includes generator differential protection, out-of-step protection and 100% stator earth-fault protection. REG615 is typically used...
