Applications
• All power generation, transmission, distribution, motor
protection applications
• Generator, Differential, Phase, Transformer, Bus, Feeder,
Breaker and Motor protection, monitoring, metering and
control
• Utility substation and industrial plant automation
• Digital Fault Recorder and Sequence of Event
• Predictive maintenance through data analysis and trending
Key Benefits
• Application flexibility – multiple I/O options, programmable
logic (FlexLogic
™
), modularity, customize to specific
requirements
• Fewer external devices required – multifunction device that
integrates protection and control functions, programmable
pushbuttons and status LEDS, and communication interfaces
• Modular construction – common hardware, reduced stock
of spare parts, plug & play modules for maintenance cost
savings and simplification
• Common platform – reduced training time and drafting costs
• Use high speed communications to reduce wiring and
installation costs – exchange inputs and outputs between
relays to achieve relay-to-relay interaction
• Cost effective and flexible access to information – multiple
communication options and protocols
• Reduce system event analyzing time and cost – sequence
of event reports, oscillography, datalogging, IRIG-B time
synchronization
• Long lasting life – when exposed to chemically corrosive
and humid environments with optional conformal coating
• Enhanced CT/VT Diagnostics – enhanced CT/VT module
diagnostics verifying the integrity of the analog signals
using an advanced algorithm ensuring reliable performance
of the relay
