Information About SEL-551

Comprehensive Overcurrent Protection
The SEL-551 provides phase, negative-sequence, residual ground, and neutral overcurrent protection in a compact package, including a complete set of instantaneous, definite-time, and time-overcurrent elements.

acSELerator QuickSet SEL-5030 Software
QuickSet helps speed up the relay application by allowing you to develop relay settings offline, program SELogic control equations, and analyze post-fault event reports.

Protection and Control Logic
SELogic control equations with SELogic variables and timers allow traditional or advanced protection schemes. Programmable local control elements permit front-panel pushbutton control. Programmable text display points provide enhanced local operator information.

Monitoring and Reporting
The SEL-551 features Instantaneous, peak, and demand metering. The latest twenty 15-cycle oscillographic data event reports and the latest 512 Sequential Events Recorder (SER) records are stored in nonvolatile memory.

Communications
The front-panel EIA-232 serial port, the rear-panel EIA-232/EIA-485 serial port, and the ASCII, binary, and Modbus RTU protocols enhance integration capabilities.
