Abstract :
The Yale University Branch held its annual electrical engineering exhibition on December 14 and 15, 1928. Some of the principal exhibits were the breakdown of air at high voltage around various types of insulators, Tesla coil, operation of power plant equipment, radio transmitter, oscillograph, electric furnace, mercury arc rectifier, and traffic control systems. Many other applications of electricity were shown and several types of class work, including industrial control apparatus, were demonstrated. On one evening, talks by engineers were broadcast by station WDRC. Nearby members of the Connecticut Section of the Institute were invited to attend, and the exhibition was well attended by Yale students and the general public of New Haven. A. F. Metzger was exhibition chairman.
