Problems associated with the interconnection of electrical power systems.

Due to its continuing rapid growth and the already large capital expenditure involved, the electricity Supply Industry is a major factor, of increasing importance in National Economy. Complex technical problems have been solved successfully in relation to long distance transmission, higher efficiency of generating plant, protection, switching, indication, communication and control. While the limits of technical development have not yet been reached, and the day to day application of existing techniques is necessary; the standardisation of specifications and designs for many individual items of plant and even for extensible generating, terminal, and distribution stations is practicable. The financial and operational benefits of standardisation of this kind are becoming more generally recognised and adopted.
