NSD570 - Teleprotection Equipment

Product catalog summary

Overview of NSD570 Teleprotection Equipment
The NSD570 teleprotection system is engineered for the rapid, reliable, and secure transmission of protection signals in high voltage power systems. It ensures selective fault isolation to maintain system stability and prevent damage, supporting various protection schemes such as direct and permissive tripping, and blocking.

Key Features and Specifications

Supports analog, digital/optical, and Ethernet/IP communication links.
Handles up to 4 independent commands in analog channels and 8 in digital/optical and Ethernet/IP circuits.
Features adaptive signal processing for minimal transmission times, high dependability, and security.
Includes continuous channel supervision and integrated event recording.
Programmable via a browser-based Human Machine Interface (HMI) for easy configuration and maintenance.
Supports remote monitoring and configuration with SNMP alarm traps.

Connectivity and Interfaces
The NSD570 is compatible with various communication media, including copper wires, optical fibers, and microwave radio links. It supports both traditional hardwired contact type interfaces and modern GOOSE messages via Ethernet, facilitating integration with IEC 61850-enabled substations.

Modular Design and Flexibility
The system's modular structure allows for easy upgrades and adaptability to different application requirements. It supports a mix of analog, digital/optical, and Ethernet systems, with options for single or redundant power supplies.

Security and Management
The NSD570 includes comprehensive measures against cyber/IT security attacks and offers secure remote access with enhanced encryption and user activity logging. It supports VLAN and priority settings for network management.

Applications
The NSD570 is suitable for versatile applications, including protection signaling over various communication media. It is designed for simple operation, with features like self-test diagnostics and a user-friendly HMI for system setup and monitoring.

Specifications
Transmit level ranges from -24 to +11 dBm, while the receive level is nominally -30 to +2 dBm with a dynamic range of 30 dB. Bandwidth and channel center frequency are programmable. The system supports digital interfaces such as V.11 / X.21 / X.24, RS-422 / RS-530 / RS-449, and G.703.1 (64 kbps, co-directional). It is compatible with E1 / T1 for direct connection to SDH / SONET multiplexers.

Optical Specifications
Optical connections include 850 nm MM with a nominal reach of 1 km and a maximum of 2 km, 1310 nm SM short haul with a nominal reach of 30 km and a maximum of 50 km, 1310 nm SM long haul with a nominal reach of 60 km and a maximum of 80 km, and 1550 nm SM long haul with a nominal reach of 120 km and a maximum of 150 km. The 1550 nm CWDM SM extra long haul has a nominal reach of 180 km and a maximum of 240 km. Optical connections can be direct fiber or via ABB-/non-ABB-multiplexers (IEEE C37.94).

Ethernet and Management
The system supports Ethernet 10/100 Mbps Fast Ethernet with auto/manual negotiation and full/half duplex options. It includes an electrical port (RJ45) and an optional optical port (SFP: 850 nm MM 0.5 to 1 km or 1310 nm SM 30 to 50 km). Management is facilitated via a standard PC and browser software, EOC, LAN, or Web with an integrated management interface. An integrated LCD display panel is optional.

Event Recording and Synchronization
The system includes an integrated, non-volatile event recorder and trip counters, capable of storing up to 7500 command/alarm events and up to 65536 counts for each command/test. Synchronization of the real-time clock is possible with inputs for external IRIG-B and 1PPS signals, and optional NTP/SNTP management interface.

Alarms and Standards
Alarms are managed with free contacts and configurable alarm allocation. The system supports IEC 61850 (Ed. 1 and Ed. 2) with a GOOSE interface for protection. It facilitates automated data exchange between substation engineering tools and the HMI570 user interface. It adheres to standards such as IEC 60834-1, EMC Directive 2004/108/EC, Low Voltage Directive 2006/95/EC, EN/IEC 61000-6-2, EN/IEC 61000-6-4, EN/IEC 60950-1, and is KEMA certified.

Power and Environmental Conditions
Power consumption is approximately 10 Watts per system in the rack. The operational temperature range is -5 to +55 ºC, with a transport and storage range of -40 to +70 ºC.
