GE / Alstom 350 Feeder Protection System

GE / Alstom Multilin 350 Feeder Protection numerical Relay 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 8 Series, 350 and P40 Agile solutions provide early fault detection and warning in this spotlight application.

The Multilin 350 is a member of the Multilin 3 Series protective relay platform and has been designed for the protection, control and management of feeders or related applications as a primary or backup protection device. This cost-effective protective device is used to perform advanced feeder protection, control and monitoring for low, medium and high voltage applications. The 350 also offers enhanced features such as integrated arc flash protection, metering, monitoring and diagnostics, preventative maintenance, advanced communications and security.
The 350 protection relay chassis used with a draw out relay is available separately, for use as a partial replacement or in test environments. The draw out relay with no chassis is also available to order as a spare unit.
