The SEL-3306 Synchrophasor Processor time correlates data from mul- tiple SEL-351 relays and concentrates the result into a single output data stream. The SEL-3378 SVP enables control applications based on synchrophasors. Directly measure the oscillation modes of your power system. Act on the ...
Coordination—Selectively coordinate with upstream relays and recloser controls using a Mirrored Bits communications link for secure, high-speed fault clearing on distribution circuits. Also, use the oscillographic event report and Sequential Events Recorder (SER) data to measure and improve protection dev...

What’s the Difference Between the SEL-351A and the SEL-351? The SEL-351A is based on the SEL-351 “family.” It has been created to offer a lower cost product and includes some specific features that provide an easy migration path from the SEL-200 series relays (specifically the SEL-...
"Schweitzer Engineering laboratories (SEL) donated the SEL 387, SEL 311L, and SEL 351S relays and the SEL AMS to Missouri University of Science and Technology. This thesis documents the demonstration approach to set the SEL 387 relay to protect a grounded wye-grounded wye transformer and then...
