Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1907 edition. Excerpt: ...requiring different E. M. F.'s, but consuming the same value of the current. Series Multiple Connection. The current, as before in a series system, is the current required by any single translating device, or any one multiple of translating devices, the E. M. F. being equal to the sum of the various E. M. F.'s demanded by the different translating devices and multiples along the line. In the " multiple-series" distribution it is possible to connect across the opposite sides of the circuit translating devices in series so adjusted that the total E. M. F. required by each series will be the same. The current required by the different translating devices in any one series must be equal, though there is no necessity for equality of current between the different series. When so arranged, single translating devices, capable of consuming the full value of the E. M. F., may be connected across the circuit in parallel with a series of translating devices, and the E. M. F. carried on the circuit is the E. M. F. required by any single translating device or any one series, the value of the current being given by adding together the currents demanded by the different series and translating devices. Each of these four systems of distribution presents its own method of regulation and special advantages. The four taken together represent all possible distinct types of distribution. In the two series systems, the plain series and the series mul tiple, regulation is effected by maintaining the current at a constant value; variations of power being produced by changing the E. M. F. of the generator to suit the demands made upon the circuit by the varying operation of the translating devices. Such regulation can be effected entirely at the generating...show more
