Feeder protection relay for simplified monitoring
Schweitzer Engineering Labs’ SEL-751 feeder protection relay is designed to let the user intuitively navigate to folders and applications with the tap of a finger and the appropriate security credentials. On the 800 × 480 pixel WVGA display, view custom bay screens that exhibit one-line diagrams, analog quantities, and digital statuses, created using the Bay Screen Builder tool in Acselerator QuickSet SEL-5030 Software. With the appropriate access level, users can control a single breaker and monitor up to five disconnects directly from the bay screen. Simplified navigation and information-rich displays make applications like comprehensive feeder protection simpler and easier to set and monitor.
In either English or Spanish, users can review phase quantities in graphic and tabular formats. Scroll through the sequential events recorder (SER), or examine an event summary. Program the auxiliary buttons to navigate to a particular screen, or set your display to rotate through as many as 16 different screens. This relay will provide years of reliable service with its operating temperature range of -40 to 85°C (-40 to 185°F), and conformal-coating option.
