Generator Protective Relay Workshop at CSU: SEL 400G Hands-On relay settings and testing for large hydrogen cooled synchronous generator.

---

Join SEL application engineers Travis Remlinger and Austin Burfield along with Doble application engineer Miguel Aguirre to design and set generator relay protective elements. Hands-On demonstration of the Schweitzer Engineering Laboratory SEL-400G Advanced Generator Protective Relay using SEL Grid Configurator software.  Then simulate/test the protective relay elements with the Doble/Manta MTS-5100 Power System Simulator and relay test set using secondary injection.
