ELECTRICAL ENGINEERING EQUIPMENT

73

This department has quarters in Engineering Hall and in the basement of University Hall. The class rooms, drafting rooms, seminary rooms, studies, and offices are in Engineering Hall. The rooms devoted to laboratory practice are in University Hall, and include the electrical measurement laboratory, the dynamo laboratory, the battery room, the photometry room, and the work shop. The electrical-measurements laboratory has masonry piers for the more sensitive instruments, and numerous conveniences indispensible to rapid and accurate measurements. In this laboratory the work relating to the measurement of current, resistance, electromotive force, the standardizing of measuring apparatus, etc., is carried on. This laboratory has been supplied with apparatus from the leading makers at home and abroad. There are several forms of bridges, resistance boxes, testing sets, non-inductive and continuously variable rheostats, and certified standards of resistance ; the leading forms of galvanometers and reading devices ; single and subdivided condensers, standard cells and electrostatic voltmeters ; hotwire instruments ; electrodynamometers ; current balances ; watt-meters ; ammeters and voltmeters for direct and alternating currents. Current is brought to this laboratory from the battery room and from the dynamo laboratory. The dynamo laboratory is supplied with power from a sixty-horse-power steam engine, which is used exclusively for the experimental work of this department. In this laboratory are to be found the leading types of direct and alternating current dynamos and motors, with conveniences for making complete tests. The equipment includes a complete ThomsonHouston 300-light alternating-current lighting plant, a complete Thomson-Houston 3-light arc-lighting plant, a complete Brush 10-light arc-lighting plant, a complete Edison 100light incandescent plant, a small 500-volt direct-current power plant, and a small single-phase alternating-current power plant. The photometry room is fitted out with a complete electric-light photometer, numerous types of incandescent and of direct and alternating current arc-lamps, and conveniences necessary for making complete tests.
