This rate can be found by trial, and when once found, the test should be repaeted once or twice to make certain that the results are correct. Phase Characteristics No Load. If the phase characteristic tests follow a heat run in which an IRT regulator has been used, it must be disconnected. The most satisfactory combination is to run two converters for this test, the one under test running as a rotary and driven by the other running inverted with a direct current loss supply. The speed and the direct current voltage are held constant by varying, respectively, the field of the inverted machine and the voltage of the loss supply. It must ke remembered that a lagging current will increase the speed of the inverted rotary, and therefore the inverted machine should be watched constantly so long as the current lags. With the field excitation of the rotary reduced to the lowest limit permitted by the inverted machine, the alternating current amperes and volts line and the direct current amperes and volts field should be read. As stated above, the speed and the direct current volts are held constant throughout the test. The field current of the rotary is increased by small increments and readings taken as above. The alternating current amperesin put will decrease rapidly until the minimum input point is reached, when they will increase again. The field excitation should then be increased until the input current has a value of at least half the full load current of the machine. Full Load. The full load characteristic is taken in exactly the same way as for no load. The direct current volts are held constant to normal rating and the amperes output constant at full load value. The field excitation is varied through nearly as...

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Commercial Electrical Testing Iiican be readily obtained. The instruments used must be of the highest quality to insure accurate results, and must frequently be compared with reliable standards work for which a standardizing laboratory is necessary. All these matters must be kept in mind and a system provided for enforcing testing regulations for obtaining clear records of the work done. In short, the testing department is a complex organization whose keynote is efficiency. Economy of labor and power, and the arrangement of apparatus are of equal importance with accuracy; with the latter, of course, a sine qua non, since the majority of apparatus tested must meet specification as regards performance, heating, efficiency, and the like. When, as often happens, more than one method can be employed in a given case, the test must be chosen which yields the maximum of accuracy practicable, consistent with the character of the work. These questions are fully considered in this little book and will appeal to all those having charge of similar departments, college laboratories, etc. To the student of engineering, however, the description of the various tests, their preparation, how they are carried out, the instruments used, and the diverse calculations required will appeal most strongly. Nearly all types of electrical machinery have been covered, and many examples have been given showing the kind of results that actually obtain in the more important cases, and the means employed for discovering electrical or mechanical faults.
