Automatic substations for heavy city service

WHEN automatically controlled substation equipment was in the development stage, the general consensus of opinion was that its greatest field lay in relieving the smaller interurban systems of a greater portion of their substation operating labor. While many such systems have installed one or more automatic substations, they have not displayed the interest in the matter that was expected. In many cases the officials have professed their total inability to finance the new apparatus even though the investment would show a very attractive saving.
