The tag line=busbar
is added to power=line
to map a busbar: the central connection in a substation
, which links all circuits of the same voltage together. Incoming power lines
and cables
, as well as transformers
and other equipment, are connected to the busbar by power lines called bays
.
A busbar assembly comprises either rigid tubular conductors or flexible conductors. Strictly spoken, the term busbar refers to just one conductor but commonly the combination of three conductors is also called a busbar, which is the definition used here.
Substations will normally have one busbar per voltage level, with the highest-voltage busbar being the most obvious, as it has the largest conductor spacing.
