Industrial Power System Protection

Protect your entire power system with rugged, reliable SEL-700 series protective relays—now with support for low-energy analog (LEA) current and voltage inputs.

With comprehensive protection and automation functions, flexible I/O and communications options, fast settings, easy mounting options, and support for both conventional and LEA current and voltage inputs, SEL-700 series protective relays are the right choice for industrial applications.

SEL-700 Series Relays: Protection for Your Entire Power System

Apply SEL-700 series protective relays throughout your system to protect generators, transformers, lines, feeders, and motors. Deploying devices that share the same platform architecture will simplify setup, configuration, commissioning, and maintenance throughout your power system.

The SEL-700 series of protective relays now supports both conventional and LEA sensor inputs.

LEA sensors for measurement of primary voltages and currents provide excellent linearity, wide-dynamic-range characteristics, reduced size, reduced weight, and enhancement of personnel safety.

For medium- and low-voltage applications that use low-energy voltage sensors and Rogowski coils or other low-power current sensors, you can order your SEL-700 series device with the combination of LEA current and voltage inputs that suits your needs.
