Protection and Control
• Fast and segregated line current differential and distance
protection functionality in a single device
• Phase segregated line current differential with adaptive restraint
and ground differential, stub bus protection
• Phase distance (five zones) with independent settings for
compensation
• Single-pole tripping, breaker-and-half with independent current
source support
• Complete generator protection with 100% stator ground fault
detection with sub-harmonic injection and field ground protection
Communications
• Networking interfaces: 10 or 100MB copper or fiber optic
Ethernet, RS485, RS232, RS422, G.703, C37.94, up to three
independent ethernet ports
• Multiple protocols: IEC 61850, DNP 3.0 and Modbus® serial/TCP,
IEEE 1588, IEC 60870-5-104 and 103, PRP, SNTP, HTTP, TFTP, EGD
• Direct I/O: secure, high-speed exchange of data between URs for
direct transfer trip and I/O extension applications
IEC 61850 Process Bus Interface
• Robust communications with up to 8 HardFiber Bricks
• Redundant architecture for dependability and security
Monitoring and Metering
• Synchrophasors in select products with IEEE C37.118 (2011) and
IEC 61850-90-5 support
• Advanced recording capabilities deliver a 1024 event recorder,
configurable and extended waveform capture and data logger
• Fault locator and user-programmable fault reports
• Breaker condition monitoring including breaker arcing current
(I2t), breaker re-strike and breaker flashover
• Metering: current, voltage, power, power factor, frequency,
voltage & current harmonics, energy, demand, phasors, etc.
