GE / Alstom 850P Multiple Feeder Protection Systems

The Multilin 850P Feeder Protection Relay is a member of the Multilin 8 Series protective relay platform and has been designed for the management, protection and control of feeder applications. The Multilin 850P Feeder Protection Relay is an integrated, one box solution, used to provide comprehensive protection, control and monitoring of underground and overhead single or dual feeders in industrial and utility power networks.

The Multilin 850P Feeder Protection Relay is also an ideal choice for bay control applications, with features including 12 switchgear control elements, a large color graphical display that supports configurable single line diagrams, an integrated annunciator panel, and 20 user configurable virtual pushbuttons.

With support for industry leading communications protocols and technologies, the 850P provides easy integration into new or existing SCADA or DCS for enhanced situational awareness. To simplify the migration and upgrade from an existing SR 750/760 or 735 protection relays, retrofit kits have been developed which significantly simplify the upgrade process.

Dual Feeder Protection
The Multilin 850D is designed for high performance protection, control and monitoring of up to two distribution feeders, and provides all the functionalities required for a distribution feeder including SOFT, under current and pole discordance. Extensive programmable logic and flexible configuration capabilities along with sequence coordination enable the 850D to comply with system coordination requirements.

850D key features
• Up to 2 feeders within one relay
• Dual voltage banks with single feeder
• High-end cyber security such as AAA, Radius, RBAC, and Syslog helps enable NERC® CIP requirements
• Draw-out design simplifies testing, commissioning and maintenance, thereby increasing process uptime
• Wi-Fi connectivity minimizes system configuration and provides safe relay programming and diagnostic retrieval
• Relay environmental diagnostic information helps reduce system downtim

Multi Feeder Protection
The Multilin 850P relay has been designed for the management, protection and control of multi feeder applications supporting both traditional voltage inputs as well as Low Energy Analog (LEA) inputs. A maximum of 4 feeders can be supported by the 850P.

The 850P Feeder Protection Relay addresses the following customer challenges:

• Extending asset life and optimizing performance for system uptime and greater return-on-investment
• Reducing system downtime due to environmental occurrences and equipment failures
• Securing CAPEX funding to update outdated systems
• Recruiting new talent to resupply the retiring / aging workforce while keeping up with technology advances
• Visibility on downstream distribution points
• Inefficient truck roll outs in event of outage

850P Feeder Protection Relay Key benefits

• Reduce number of IEDs in the system, resulting in lower capital and O&M costs, and smaller battery sizing
• Mean time to repair less than 15mins with field swappable PSU, draw out construction and ready to consume service reports
• Extend asset life with built-in environmental monitoring, battery and advanced breaker monitoring
• Same device-based solution (850D/P) reduces training needs, standardizes SKUs and harmonizes the user and operational experience
