I would recommend SEL products as well. I have been commissioning systems (up to 500 kV) and the SEL product continues to become more prevalent. As another person mentined, once you learn 1 relay commands, you know all relays. I would stay away from SCADA systems and utilize communications...
Programma makes a nice unit called the Egil.
This is especially well suited for MV breakers.
Others are designed for HV/EHV breakers and thus are more expensive.
