The short tripping time is especially advantageous for applications with high fault levels or where fast fault clearance is required for power system stability.The modular hardware allows the protection to be optimally matched to the busbar configuration. The decentralized arrangement allows the cabling costs in the substation to be drastically reduced. The 7SS52 busbar protection caters for single, double or triple busbar systems with or without and quadruple busbar systems without transfer bus with up to: 48 bays, 16 bus couplers, and 24 sectionalizing disconnectors and 12 busbar sections.<\/p>\n<h2>SIPROTEC 7SS52 BUSBAR PROTECTION FUNCTIONS<\/h2>\n<ul>\n<li>Busbar differential protection<\/li>\n<li>Selective zone tripping<\/li>\n<li>Very short tripping time (&lt;15 ms)<\/li>\n<li>Extreme stability against external fault, short saturation-free time (?2 ms)<\/li>\n<li>Phase-segregated measuring systems<\/li>\n<li>Integrated check zone<\/li>\n<li>48 bays can be configured<\/li>\n<li>12 busbar sections can be protected<\/li>\n<li>Bay-selective intertripping<\/li>\n<\/ul>\n<h3>7SS52 BREAKER FAILURE PROTECTION FUNCTIONS<\/h3>\n<ul>\n<li>Breaker failure protection (single-phase with\/without current)<\/li>\n<li>5 operation modes, selectable per bay<\/li>\n<li>Separate parameterization possible for busbar and line faults<\/li>\n<li>Independently settable delay times for all operation modes<\/li>\n<li>2-stage operation bay trip repeat\/trip busbar<\/li>\n<li>Intertrip facility (via teleprotection interface)<\/li>\n<li>Low-current mode using the circuitbreaker auxiliary contacts<\/li>\n<\/ul>\n<h3>SIPROTEC 7SS52 BUSBAR PROTECTION ADDITIONAL PROTECTION FUNCTIONS<\/h3>\n<ul>\n<li>End-fault protection with intertrip or bus zone trip<\/li>\n<li>Backup overcurrent protection per bay unit (definite-time or inverse-time)<\/li>\n<li>Independent breaker failure protection per bay unit<\/li>\n<\/ul>\n<h3>FEATURES<\/h3>\n<ul>\n<li>Distributed or centralized installation<\/li>\n<li>Easy expansion capability<\/li>\n<li>Integrated commissioning aids<\/li>\n<li>Centralized user-friendly configuration\/parameterization with DIGSI<\/li>\n<li>Universal hardware<\/li>\n<\/ul>\n<h3>COMMUNICATION INTERFACES<\/h3>\n<ul>\n<li>FO interface<br \/>\n&#8211; IEC 60870-5-103 protocol<\/li>\n<li>Electrical interface<br \/>\n&#8211; IEC 61850 protocol with EN 100 module (firmware V4.6)<\/li>\n<\/ul>\n<p><a href=\"https:\/\/reliservsolution.net\/home\/product-category\/siemens-numerical-relays\/siprotec-4\/\">SIPROTEC 4<\/a> leads the way in integrating protection, control, measurement, and automation functions in one device.
