Electricity-supply distribution - trimming for efficiency

Area Electricity Boards can only influence a small proportion of their total operating costs by improving operating efficiency. Ways of improving efficiency include better use of manpower, use of computers for dealing with economic and technical matters, lowering of engineering costs by increased standardisation and exploitation of new materials and techniques, and the centralisation of meter-testing facilities. Future contributions to improved efficiency include ripple control, automatic supervision and telemetering, and the use of new types of switchgear.
