BINARY TELEPROTECTION
OVER IP/MPLS

Features and Highlights

• IP/MPLS Network Interface to provide “Distance Protection” over IP/MPLS Network.
• IP / MPLS Network Interface - Includes both 10/100BaseT (Electrical) Ethernet and 100BaseFX (Optical) Ethernet options.
• Less than 6ms back-to-back operating time (including relay operating time) over IP/MPLS Interface
• 4/8 independent-simultaneous command channels which may be configured to operate selectively or simultaneously over IP/MPLS Network
• Compact, standard 19-Inch Rack-mountable, 3U high chassis
• Distance Teleprotection applications over IP/MPLS
• User programmable for Direct Tripping, Permissive Tripping and Blocking Protection Schemes
• Compliant with IEC 60834-1 and IEC 834-1 specifications and standards for reliability
• Error resistant transmission
• IRIG-B Time / NTP Synchronization.
• Available with Trip Digital Display Counters (8/16) with 8 user configurable External Relay Alarm outputs
• Full Duplex Operation.
• Available with 48V DC, 110V DC, 220V DC and 250V DC command and switching voltage options.
• Option of 1+1, Redundant Power Supply.
• Available with 48V DC, 110V DC, 220V DC and 250V DC power supply options.
• Immunity to Voltage Dips, Short Power Supply Interruptions and Voltage Variations as per IEC 61000-4-11 specifications.

Performance:

• Less than 2ms command transfer time.
• Less than 4ms relay operating time.
• Less than 6ms back-to-back operating time (including relay operating time) over IP/MPLS interface.

Flexibility and User Programmability:

• User programmable parameters for “Input” command sampling time and “Output” command holding time.
• Input Sampling Time - Sets the “Sampling Time” of the INPUT Commands.
• Output Holding Time - Sets the “Holding Time” of the OUTPUT Commands.
• Output Extend Time - Sets the “Minimum Deactivation Time” of the OUTPUT Commands.

Event and Alarm Logging:

• Time-Stamped Alarm Logging.
• Time-Stamped Event Logging.
• IRIG-B time / NTP synchronization option to synchronize time-stamps with GPS.

Maintenance:

• Manual Loop Test This feature initiates a “Manual Loop-Test” of the transmission link that interconnects the “Local” Teleprotection Terminal and the “Remote” Teleprotection Terminal
• Automatic Loop Test The Automatic Link Test feature automatically initiates “Periodic Loop Tests” at user programmed intervals of the transmission link that interconnects the “Local” Teleprotection Terminal and the “Remote” Teleprotection Terminal
• Delay Measurement This feature automatically initiates an end-to-end “Delay Measurement Test” between the “Local” and the “Remote” Teleprotection Terminal through the interconnecting transmission link.

Access and Monitoring:

• Command Line Interface (English text commands).
• Telnet
• SSH
• SNMPv2 Traps.

Operations and Management (OAM):

• RS232 serial interface for local terminal access
• USB serial interfaces for local terminal access
• 10/100BaseT Ethernet Interface for remote access over an IP network.

Management and Monitoring:

• RS232 serial, USB serial interfaces for local terminal access
• 10/100BaseT Ethernet Interface for remote access over an IP network
• Encrypted Password Protection
• Maintains an access log of over 10,000 most recent entries for security audit
• Telnet - Remote access over IP links
• SSH - Secured remote access using “Secure Shell Protocol” over IP links
• SNMP Traps and NMS for real time remote monitoring and management over an IP network
• 8, Dry contact external alarm relay to connect external alarms on an annunciator panel to extend audio and / or visual alarms – Optional
• Trip Counter Display
