bus is a conductor which enables you to draw as many
syncronised 3-ph lines (o/p lines) from a single 3-ph
connection (i/p line). at the distribution station it is
required to increase the no 3-ph lines so as to supply
power to various areas in the city via feeders. here each
feeder is for each area and it feeds power through the 3-ph
connection drawn from the bus bar.
