The SIPROTEC 7SS85 busbar protection is a selective, safe and fast protection against busbar short circuits in medium, high and extra-high voltage systems with a large variety of busbar configurations. Busbar protection devices SIPROTEC 7SS85 are part of the modular SIPROTEC 5 series and their main function bases on the principle of differential protection. Additional protection and control functions extend the scope of application to a comprehensive station protection. The flexibility of the functions and the modular hardware structure allow an optimum adaptation of the 7SS85 to the most various system configurations and functional requirements.
Functionality The centralized busbar protection SIPROTEC 7SS85 encompasses the following maximum quantity structure: 20 3-phase measuring points (current transformer) 4 3-phase measuring points (voltage transformer) 26 bays (feeders, couplers, bus-section disconnections) 6 bus zones (busbar sections with measuring function) 6 couplers (with 1 or 2 current transformers) 3 auxiliary busbars (busbar sections without measuring function) Phase-selective measurement and Display Selective tripping of faulty busbar sections Optional additional decentralized binary in- and outputs via protection interface (PI) or IEC 61850 (GOOSE) provide new concepts for busbar protection
