Abstract
THE SELECTION of a rectifier substation for the conversion of alternating current to direct current for the purpose of supplying power for cutting, loading, and hauling coal in mines is a problem to be studied from the standpoint of voltage drop, losses, economics, and maximum loads. From this, and actual field tests and data, the conclusion is reached that for average mining conditions, the optimum size rectifier substation is 300 kw.
