Automatic control for substation apparatus

The use of automatically operated stations has become quite general over the country, but as the development has been very rapid, and the engineers involved so busy with their individual problems, very little has been accomplished toward the pooling of ideas and experiences. This paper outlines some of the more important problems being encountered in automatic development such as the need for automatic fire protection in the stations, the necessary future development of thermal protective devices, voltage regulating devices, etc. Particular stress is laid on the fact that, while we have some problems which we presume have been worked out, some of the solutions are far from perfect. This paper is prepared in a manner which, it is hoped, will bring out many valuable ideas in its discussion.
