	[[Transformer]]s lower the very high transmission [[voltage]]s into a voltage less than 10 000 [[volt]]s, which is suitable for [[distribution system]]s. Substations are also often equipped with a bus that splits off the current in multiple directions, as well as [[circuit breaker]]s and switches which will allow the isolation and direct control of certain parts of the transmission and distribution systems.<ref name=a/> Many substations also include [[capacitor]]s to smooth the voltage output.
