How we helped
SynchroGrid designed the replacement of reactor relays GE T60 and SEL 487E-0 to be replaced with SEL-387E and SEL-487E-3 relays respectively at Cross Texas Transmission’s Gray Substation by making appropriate modifications to drawings, relay settings, GOOSE communication files, and reports.
The process involved the following:
- Updating the control schematics and drawings – relay one-lines, three-lines, communication interconnection drawings, terminal block diagrams, and wiring diagrams
- Creation of relay settings for SEL-387E relays to coordinate, replacing GE-T60 relays
- Creation of relay settings for SEL-487E-3 relays to coordinate, replacing SEL-487E-0 relays
- Updating the architect file to coordinate GOOSE communications between relays
