What reading level is Underground Transmission And Distribution for Electric Light And Power book?
To quickly assess the difficulty of the text, read a short excerpt:
Of Baltimore in sections of their conduit system where cable burnouts were frequent. Most of the troubles in this part of the insulation were due to the high temperature of the duct line during the summer months. The soil around the ducts FIG. 92. Duct temperature before installing cooling system.
was to a great extent dried out and it seemed logical to conclude that some method of supplying water to the duct line would improve conditions. Studies were made of the temperatures existing in the d...uct line under regular operating conditions. The conduits which were used principally for carrying 13, 000- volt cables were laid in made earth with some ash. Thermome- ters were placed in an idle duct some distance from a manhole and the observations showed that the temperatures in the duct line responded to the variations in load and to atmospheric 208 UNDERGROUND TRANSMISSION AND DISTRIBUTION temperatures. The response to the changes in load followed within a few hours, but atmospheric temperature variations produced no effect for some days.
