In this video we go over how to set up a directional control element and use it to torque control a ground inverse-time overcurrent element using the SEL-351S protective relay.

Your videos are badass, sir. I am working on becoming a P&C tech myself and your content has really been helping me learn how this all works. Thank you.

[@romeroengineering]

Thanks! I'm glad our videos are helping you in your career.

[@albertovaldivia4230]

Great content. Keep the good work. This information is fundamental for people on the P&C area and not reachable in accesible plataforms like youtube or your course channel. Congratulations🎉

[@romeroengineering]

Thanks!

[@edgarosorio3817]

Just the video I was waiting for. Thanks
What about the torque control settings on the relay?

[@christopherserojano3953]

Thanks very much @Romeroengineering! Very good video. Most SEL relays have 50/51 element for non-directional, and 67 for directional overcurrent. Is it okay to use it like 67G1T for level 1 trip?

Good evening mr Romero
Could you please share all application(software programm) that you use in rela y protection engineering

[@romeroengineering]

Hi! For developing relay settings, you'll need to use the software from the specific manufacturer. For example, SEL AcSELerator Quickset for SEL relays. For short circuit and protection coordination, we typically use ETAP, ASPEN, CYME, or CAPE.
