SIPROTEC 7SD5 - The benchmark for line protection
Features:
1. The protected differential zone may be easily extended from 2 up to 6 line ends. Complex system configurations receive clearly defined protection zones and maximum fault coverage.
2. The high-speed distance relay operates fully independent from the differential relay. Back-up zones provide remote back-up for upstream and downstream lines and other power system components.
3. Contrary to traditional measurement approaches, the distance-to-fault locator uses measurement quantities from both line terminals. This results in precise readings, even under difficult system conditions, e.g. parallel lines or resistive line faults fed from both line terminals. The
readings are available right after fault clearance for quick line clearance and system restoration.
4. The relays provide optical ports for relay-to-relay (R2R). The adjustment to other communication media takes place via media converter. They accept all traditional and modern communication media, i.e. fibers, comms networks and pilot wires. The relays remain unchanged.
5. For multi-ended lines the communication links may be operated in open or closed rings. The latter provides communication even if one link is broken. SIPROTEC has the right answer to dependable transmission line protection and distance-to-fault
