GE is proud to announce that the Multilin™ 3 Series platform of protection and control relays has been enhanced to provide new protection, control and communications, enabling increased safety and maximum process uptime.
With high speed integrated arc flash protection for various switchgear compartments of feeders, the personnel safety is enhanced. Traditional selectivity methods may not provide fast and accurate protection. Arc energy, which is a result of a fault, can endanger people and asset life and impacts power system reliability.
The Multilin 350 supports an integrated arc flash module providing constant monitoring of an arc flash condition within the switchgear. The 350 is able to detect light and overcurrent using 4 arc sensors connected to the relay. In situations where an arc flash/fault does occur, the relay is able to quickly identify the fault and issue a trip command to the associated breaker(s) thereby reducing the total incident energy and minimizing resulting equipment damage. Self-monitoring and diagnostics of the sensors ensures the health of the sensors as well as the full length fiber cables.
Other highlights include:
- Extend switchgear life - with fast and secure arc flash detection reducing the total incident energy and minimizing resulting equipment damage
- Enhanced control and monitoring - supporting phase-segregated elements and optional programmable LEDs for non-draw out products
- Increase process uptime - with options for chassis without the relay and draw out relay without the chassis for spare parts, replacements, or testing purposes
