System Protection


How we helped

SynchroGrid developed relay settings for transformer protection, bus protection, and feeder protection at a local substation. Relay coordination was also provided for the transformer and distribution feeder to ensure optimal performance.

The process involved the following:

  • Creating relay settings for transformer relay SEL-387A
  • Developing relay settings for bus relay SEL-351
  • Producing relay settings for high-side interrupting device protection SEL-501
  • Generating relay settings for transformer metering relay SEL-734P
  • Creating relay settings for transformer logic processor SEL-2100
  • Developing relay settings for feeder relays SEL-351 and SEL-551
  • Establishing relay coordination between transformer and feeders
  • Authoring relay setting reports
