Monitoring functions
Monitor self-supervision of the relay, trip circuit supervision (74TC), 8 oscillographic fault records, CT-secondary current supervision, event logging / fault logging and switching statistics.
The SIPROTEC 7SD610 relay provides differential protection for lines, cables and transformers across all voltage levels and network types.
The SIPROTEC 7SD610 protects electrical systems from diverse faults using high-speed, phase-selective short circuit measurement for rapid, precise clearance of single-phase and three-phase faults. Provide reliable protection for complex applications like series and parallel compensated lines.
Enhance system reliability with two independent differential stages: sensitive high resistance fault measurement and fast high current fault clearing. Digital data communication via fiberoptic cables or pilot wires extends protection over long distances.
This product is currently being phased out. Contact your Siemens representative for details.
Deploy the SIPROTEC 7SD610 for universal use with power lines and cables on all voltage levels. Protect your network and minimize downtime.
Flexible retrofitting of communication modules helps you fit existing configurations. Integrate with your current systems and future-proof your protection infrastructure.
Expect fast and effective fault clearance with two independent differential stages. Improve safety with sensitive measuring for high resistance faults and rapid response to high current faults.
Monitor self-supervision of the relay, trip circuit supervision (74TC), 8 oscillographic fault records, CT-secondary current supervision, event logging / fault logging and switching statistics.
Utilize fiber optic cables, networks or pilot wires for differential current measurement, allowing line ends to be far apart. Adapt the serial protection interface to various communication channels.
Beyond differential protection, the SIPROTEC 7SD610 includes emergency and back-up functions. These include phase and earth overcurrent protection, overload, under/over-voltage and breaker failure protection.
