GE D60 | Line Distance Protection System
High-speed transmission line protection with single/three-pole tripping The D60 is suitable for protecting transmission lines and cables including lines equipped with series compensation. The D60 supports dual-breaker applications and can be applied in single-pole or three-pole tripping applications. The D60 is applicable to different teleprotection schemes and includes inter-relay protection communications via direct fiber as well as different interfaces. The D60 also provides synchrophasor measurement over Ethernet per IEEE C37.118.
Applications
- Overhead lines including series compensated lines and underground cables of different voltage levels
- Single and dual-breaker circuits requiring single/three-pole autoreclosing and independent synchrocheck
- Circuits with in-zone power transformers and tapped transformer feeders
- Secure application with Capacitively-Coupled Voltage Transformers (CCVTs)
- Backup protection for generators, transformers and reactors
Key Benefits
- High-speed, cost-effective five zone quad or mho, phase and ground distance protection
- Reliable and secure protection on series compensated lines
- Superior phase selection algorithm ensures secure high-speed single-pole tripping
- Supports multiple standard and customizable pilot schemes for fast fault clearance within the protected zone
- Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
- Flexible programmable logic for building customized schemes
- Simplified teleprotection interfaces with direct I/O communications hardware for transfer trip and pilot-aided distance schemes
- Phasor Measurement Unit (synchrophasor) according to IEEE® C37.118 (2011) and IEC® 61850-90-5 support
- Three independent fiber or copper Ethernet ports for simultaneous/ dedicated network connections with advanced 1 microsecond time synchronization via LAN with IEEE 1588 support
- Complete IEC 61850 Process Bus solution provides resource optimization and minimizes total P&C life cycle costs
- Embedded IEC 61850 protocol
- Increase network availability by reducing failover time to zero through IEC 62439-3 "PRP" support
