ELECTRICAL ENGINEERING.

UP-TO-DATE APPARATUS FOR CANTFvRBURY COLLEGE. Much valuable work has b»n done by the School of Engineering and Technical Science, connected with Canterbury College, but the proposed addition of a quantity of un-to-d-te electrical apparatus to the school appliances gives promise of even better reButts* in the near future. The establishment of a department dealing with electricity and 'electric;!l engineering is no new idea with the College. When drawing up the syllabus of lecture., for m-erhanioal engineering student)* in 1883, Professor Scott, the professor in charge, provided for a course in electric light and tromn.-S-.i--n of power as an ad<Ktion.il qualifying subject for the students. In fact. Professor Scott's special acquaintance with this nubject of electrical engineering seems to have been a factor in influencing the Board when it offered him the chair of the iwrw department of engineering, which was originated in Octobtj-, 1889. Ever siuce that time this coui__- has remained ou the syllabus, but tlie college governors have not. until quite recently, been in a position to supply the n-ecesfwry apparatus to enable th*? work to be .properly fcak-.ii up. In April of hist year, by reason of the separation <>f the chair of chemistry and ph.vsii.-i, (he Board d.cided to hand over the teaching of the whale subject of electricity to the depurtmt-nt of engineering, and to give Professor Scott an amrietaut in this Einicular wo:k. in the p;r<on of Mr. A. . Cradt-iX'k. an old student of the school. Tim, of course, also meant providing nece.* awry apparatus. Professor Scott has just returned fvoiu Sydney, when* he made arrangement., withthe agents of tin Westinghoiwe C'onijKuiv of America {well known in connection with thc Niagara Power Transmission tSohc-me), for the supply of a very thorougli equipment of experimental electrical apparatus. To render this plant as complete a< possible, the -Profe-sor has decided to have an expu-vimcutul light metallation of sufnkient- capacity to light tire laboratories ur.oe_* hi.-* control. This plant will be oompltte in itself, and driven by aflu. engine, and arrangements will bs made for the students in e__ctrical engineering to be solely re**porrsi!ble for the working of tho plant. In this w.iy they will get a thor- ! ouuh m*i_h l into the practical working of j electrical installation.

In addition to this tiurewiil be a continuation current power transmission plant, one of the features of which will be an experimental dynamo embodying some novel points of construction. This is b.ing made in accortlance with -ps-ciii'-atioM prepared by Professor Scott, and will be arranged in such a w»y tb.it it can be worked either as a series, a. shunt, or a i*ompound-wound machine. The shunt being divided in sections to excitato the degree of compounding, put be varied within wide limits. In addition to this experimental dynamo, there aro shunt and seri«.s motors of 2_ horsepower capacity each. The great importance of polyphase transmission has led to a polyphass plant on very complete lines being ordered. This consists of __n experimental alternator of 7£ .horse-power, capable of giving a on*, two. or three .-phase current; » two phase induction motor of 3 horsepawer, and a tli-ree i>ha«e induction motor of 3 horse-power. There is also a motor generator of 3 horse-power, and a special series of tra__-.oro.an, designed by Mr. Bradford, electrician 'of the Westinghouse Company, capable of transforming a 220 volt current of the alternator to one, two, or four _h-iu_tand two hundred volts, a pressure altog..h-.r too -ugh HF__/r indfacriini ftwte use by rtudwnrts or in the laboratory. To lurcommodate this new apparatus on extension of the present building will be necossary. and it i» proposed to add to the portion of the structure now devoted to the mj&UTroer-t* of the students at the School of J.-_gii_»ring and Technical Science.
