Now, lets go through a industrial single line diagram. When interpreting a single line diagram, you should always start at the top where the highest voltage is and work your way down to the lowest voltage. This helps to keep the voltages and their paths straight. To explain this easier, we have divided the single line into three sections.
However, the bus bar phase is also related to electrical power distribution. Bus bar systems use more than one busbar per phase.
