SIPROTEC 7SS52 numerical protection is a selective, reliable and fast protection for busbar faults and breaker failure in medium, high and extra-high voltage substations with various possible busbar configurations.
The protection is suitable for all switchgear types with iron-core or linearized current transformers. 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 isolators and 12 busbar sections.

The 7SD610 relay is a differential protection relay suitable for all types of applications and incorporating all those functions required for differential protection of lines, cables, transformers and busbars. Transformers and compensation coils within the differential protection zone are protected by means of integrated functions, which were previously to be found only in transformer differential protection.

It is designed to provide protection for all voltage levels and types of networks; two line ends may lie within the protection zone. The relay features very high-speed and phase-selective short-circuit measurement. The unit is thus suitable for single-phase and three-phase fault clearance.
Digital data communication for differential current measurement is effected via fiber-optic cables, networks or pilot wires connections, so that the line ends can be quite far apart.

Safety-implemented circuits must be control reliable as mandated in U.S. and European standards. Control reliability is not provided by simple redundancy. There must also be monitoring of the safety circuitry to assure that redundancy is maintained. Monitoring may be achieved by using Omron STI safety monitoring relays that range in function from two-hand palm button control to dual channel input units with time-delayed outputs that conform to ANSI B11.19-2003, Section 6.1 for Performance of the Safety Related Function(s). All safety relays carry the CE mark and are designed to incorporate three points of safety in their operation to meet both European and U.S. requirements. All safety relays are UL and C-UL listed.
