• Transmit message modifications

• New transmit messages• Relay logic updates

What Impact Do Settings Modifications Have on Test Validation?

• Logical subscription mapping patterns prevent and identify virtual wiring errors

• GOOSE signal isolation is critical to in-service testing• System visualization aids in testing

Summary

• GOOSE system verifications should be documented in test plans

• GOOSE signals should be documented in drawing packages

• Design should allow expansion and minimize retesting
