Some theoretical considerations of power transmission

The following points are developed in the paper: 1. A proof of the circle diagram maintaining therein the idea of the angle between the generator and receiver voltages. 2. It is shown how the characteristics of the synchronous condenser limit the maximum power that can be transmitted over a line. 3. The effect of character of load on stability. 4. Comparison of 500-mile straightaway line with 500-mile line with condenser at mid-point.
