Feeder Protection

GE’s distribution feeder protection systems provide advanced protection with flexibility, programmability and communications for maximum system reliability. Our highly skilled engineers and technicians understand distribution feeder principles and the sources of faults on overhead and underground distribution feeders. They apply their knowledge to the design and manufacture of some of the most advanced protection relays and systems in the world.

Major faults occurring in the distribution system such as arc flash, incipient cable splice fault, high impedance fault and others, must be sensed quickly and isolated immediately to prevent hazards to the general public and personnel. Learn how GE’s Multilin A60, F60 and 750 solutions provide early fault detection and warning in this spotlight application.
