SynchroGrid developed relay settings for transformer protection, bus protection, feeder protection and bus tie protection as well as providing relay coordination for the transformer and distribution feeder.

The process involved the following:

  • Creation of relay settings for transformer relay SEL-387A.
  • Creation of relay settings for bus relay SEL-351
  • Creation of relay settings for high side interrupting device protection SEL-501
  • Creation of relay settings for transformer metering relay SEL-734P
  • Creation of relay settings for transformer logic processor SEL-2100
  • Creation of relay settings for feeder relays SEL-351 & SEL-551
  • Creation of relay settings for bus tie relays SEL-351 & SEL-551
  • Creation of relay settings for under frequency/under voltage relays SEL-351A & SEL-2440
  • Relay coordination between transformer & feeders
  • Creation of relay setting reports
