Text Appearing Before Image:
e generator panels at the other end. A totalizing panel is gener-ally put in the middle of the exciter panels on which are mountedinstruments to show the total output of all the exciters working to-gether, while a totalizing panel for the purpose of registering thetotal output of the generators is put in the middle of the generatorpanels. There have been a number of methods suggested for switch-board and switching connections, some of which are highly com-plicated; and the multiplicity of connections and the numerousswitches are more liable to prove sources of trouble than to beof much assistance. Furthermore, high-tension switches are ex-pensive and, unless carefully worked out, the switchboard may bea source of great and unnecessary expense. Fig. 73 shows anarrangement which the author considers amply complete andflexible. Gv G2, and G3 are three-phase generators excited by fieldsFv F2, F3. The generators connect through the generator switches SWITCHING AND CONTROLLING APPARATUS 145

Fig. 73. 10 146 DEVELOPMENT AND DISTRIBUTION OF WATER POWER to a set of three-phase, low-tension bus-bars. Tv T2, TBJ T4 arestep-up transformers connected in mesh as shown, and any trans-former may be joined to the low-tension bus-bars by means of thelow-tension transformer switches which connect to the transform-er primaries. These generator and transformer switches maybe ordinary knife switches if the voltage of the generators doesnot exceed 600 volts and the K.W. capacity is not above 500.It is well, however, to use automatic circuit breakers, which maybe tripped by hand, for the generator switches, and these will dis-connect in case of overload or can be operated manually whendesired. A set of high-tension bus-bars has a series of high-tensionswitches connecting them to the step-up transformer secondaries,and the outgoing transmission lines are joined to the high-tensionbus-bars by high-tension switches similar to those connecting thetransformer secondaries to the high-tension bus
