CO tA Preface - In this Thesis tne author has endeavored to compile from various sources a set of experiments for both direct and alternating current laboratory work, to list the apparatus required, to lay out tne floor plan and dis- tributing system of the laboratory, and to design the test- stands and tne switchboaras. In prepsring the following set of experinents no attempt was made to go into detcil, or to prescribe how the experiment snould be conducted. Tnis was left to the discretion of the instructor in charge, wno cen out- line the experiment to suit the existing conditions, Hovw- ever, free use has been made of laboratory text-pooixs, and such trade publications as made possible the compilation of = set of experiments that will acquaint the student with the characteristics of the different kinds of elec- trical apvaratus. s'rom the same sources a list was made of the a»paratus necessary to perform each experiment; and tne text-boolks in which a discussion of the experi- ment may be found were noted for future reference. In laying out the floor plan and distribut- ing system, illustrations of the electrical laboratories at other institutions and of tne one recently destroyed here were referred to freely. Yhe future develonment of the laboratory was considered in plenning the arrange- » ment of the cpparatus, so that any cnange or rearrange- ment necessary mey be easily made witnout detracting 102634 from the anpearance of the laboratory. in the design of the test-stands, machines saved from the recent fire were measured and manufactur- ers' bulletins and leaflets have been consulted for the dimensions of the avparatus likely to be used upon them. the faults of the piers used in the former laboratory were considered and an attempt was made to overcome these defects in the design of portable and rigid stands. In the design of the switchboards reference was made to illustrations of switchboards at other insti- tutions, to tne one recently destroyed here and to svitch- boards in power plants.
