Romero Engineering Company on Instagram: "Breaker failure schemes start with the BFI signal. BFI tells the relay that the breaker has been commanded to trip. That command may come from multiple relays, such as a feeder relay or a bus differential relay. All trip sources must be included in the BFI logic so breaker failure protection operates correctly. #BreakerFailure #PowerEngineering #ProtectionRelays #SEL751 #SEL487B #ElectricalEngineering"

Romero Engineering Company on Instagram: "A feeder breaker is not tripped by just one relay. In this example, the SEL-751 trips the breaker for feeder faults, while the bus differential relay trips the same breaker for bus faults. Knowing every trip source to a breaker is essential for proper breaker failure protection design. #BreakerFailure #PowerEngineering #ProtectionRelays #SEL751 #SEL487B #ElectricalEngineering"
