Applications
• Primary protection for distribution feeders
• Stand-alone or component in automated substation
control system
• Interlocking scheme on distribution level by means of
Remote I/O features
• Throw over schemes (bus transfer scheme)
• Load shedding scheme based on frequency elements
Key Benefits
• Unparalleled security/safety – downed conductor detection
• Reliable Distributed Generation interconnection protection
• Dependable and secure – performance backed up by
many years of field experience
• Cost effective and flexible access to information – multiple
communication options and protocols
• Breaker monitoring – monitor breaker conditioning
through analog I/O, rich metering, breaking arcing current,
and trip counters
• Use high speed communications to reduce wiring and
installation costs – exchange inputs and outputs between
relays to achieve relay-to-relay interaction
• Reduce installation space requirements through compact
design – multifunction device that integrates protection
and control functions, programmable pushbuttons and
status LEDS, and communication interfaces
• Maintenance cost savings and simplification – modular
construction, common hardware, reduced stock of spare
parts, plug & play modules
• Application flexibility – multiple I/O options, programmable
logic (FlexLogic
™
), modularity, customize to specific
requirements
• Reduce system event analyzing time and cost – sequence
of event reports, oscillography, datalogging, IRIG-B time
synchronization
• Embedded IEC 61850 Protocol – no external protocol
converter required
Features
Protection and Control
