Data Sheet - The SEL-351A Protection System provides an exceptional package of protection, monitoring, control, and fault locating features. The SEL-351A-1 Protection System offers an economical, yet impressive feature subset of the SEL-351A. The SEL-351A-1 offers the same functionality as the SEL-351A, except without directional elements, synchronism checking, load encroachment, station battery monitoring, and sensitive earth fault elements.
Data Sheet - Complete System for Control and Monitoring - The SEL-2440 Discrete Programmable Automation Controller (DPAC) withstands harsh physical and electrical environments and is built and tested to meet mission-critical IEEE and IEC protective relay standards. Apply the DPAC to satisfy stand-alone or distributed input, output, and communications needs.
