Outdoor substations in the Middle West

Conditions in the Middle West, particularly in the agricultural districts, have often been such as to necessitate the construction of small 33,000-volt outdoor substations in order to make the supply of current commercially practicable. These stations have been constructed with very simple switching and protective equipment, and economy of design and protection to the main line have been the dominating feature of design. Operation of such stations has been successful and they are of great benefit to the communities served. Improvement in lighting and overload protection is looked for.
