A bus coupler is a device which is used to couple one bus to the other without any interruption in power supply and without creating hazardous arcs. A bus coupler is a breaker used to couple two busbars to perform maintenance on other circuit breakers associated with that busbar.
Both ends of the bus, whether it includes one coupler or a series of couplers connected together, must be terminated (in accordance with MIL-STD-1553B) with "a resistance, equal to the selected cable nominal characteristic impedance (Zo) ± 2.0 percent." This is typically 78 ohms.
With electrical media HS buses, the physical architecture is like that with 3838/1553B, save that the central repeater has to be at one end of each of the collector and distributor lines: the RT's connections to these lines work preferentially in one physical direction along the bus - hence directional couplers.
In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks .
At the two ends of the bus, resistors connect between the positive (high) and negative (low) signal wires either in internally terminated bus couplers or external connectorized terminators. The MIL-STD-1553B bus must be terminated at both ends to minimize the effects of signal reflections that can cause waveform distortion and disruption or ...
An active search is underway for a 66-year-old Michigan woman who disappeared from a popular tourist hot spot during a trip to the Grand Canyon more than a week ago, officials said.
After about an hour of waiting, Schneider said the students moved to wait inside the school bus outside. Ultimately, the group ate its lunch back at the elementary school. Cracker Barrel dismisses ...
A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.
