Abstract
THE type of construction used for substations is generally governed by requirements, for example, fire and air-raid precautions, which may conflict with the maintenance of the atmospheric conditions necessary for keeping the equipment in good order. These conditions are not necessarily the same as those needed for human comfort, and the application of heat alone has often been found to be ineffective and costly. In a paper read in London before the Institution of Electrical Engineers, F. Favell and E. W. Connon record their experiences in overcoming substation ventilation problems in particular cases. Adequate and suitably planned ventilation will maintain substation equipment in a satisfactory condition with a far smaller use of heat than has generally been considered necessary. Further collaboration by manufacturers, for example, in designing gear which would be unharmed by the occasional condensation that might occur in an unheated building, might enable heating to be dispensed with entirely. It is not certain that present-day switch-gear will be affected adversely by occasional bad conditions, and further investigation of this matter is required. Substation equipment and the buildings housing it should be designed and constructed as a complete unit. The paper discusses the subject under the headings of typical arrangement of a large indoor substation, conditions required in substations, the effects of unsuitable conditions, arrangements of ventilating plant, transformers inside buildings, and application to smaller substations.
