Temperature Rise and Losses in Solid Structural Steel Exposed to the Magnetic Fields from A-C. Conductors

from loops formed by multiple ground connections. In some instances the circulating currents produced points of incandescence at high resistance joints in the metal framework. Heating was substantially re duced by removing from each section all grounds except one and opening the metallic circuit of the ironwork at intervals to prevent forming of loops.No attempt was made to measure temperatures in conduit and in reenf orcing steel due to their inaccessi bility. However, all parts of the building were carefully examined by hand for elevated tempera tures, but none were found, so it was assumed that the protective devices were functioning successfully.
