Baseline Media on Instagram: "Singapore bagged a second medal in multisport today, with a silver in the Aquathlon Men’s Relay. It was an exciting race all the way, keeping spectators on the edge. The starting boys came out of the water as a pack, with Indonesia pulling a slight lead over Singapore’s Luke Chua (@luke.chuaa) at the end of the run. Over to Tey Yi Jun (@yijun.tey), he never gave up the chase and managed to close the gap and take the lead by a second. After that, Bryce Chong (@brycec

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"
