Methods of voltage control of long high-voltage lines by the use of synchronous condenser

The following points are covered in this paper: Inherent characteristics of high-voltage lines and high-voltage transformers. Effect of low power factor load on high-voltage lines as to limiting capacity and uses of condenser for increasing line output and obtaining good voltage control. Characteristics which must be met by generators, condensers and regulating equipment in order to control properly voltage over all operating conditions.
