ANSI/AIM Code 128 Generator In .NET Using Barcode drawer for .NET framework Control to generate, create Code 128A image in VS .NET applications. In Fig. 254, A 0 , B 0 , and C 0 denote the three wires of the outgoing transmission line. Actually, in diagrams such as the above, in which operation is at 60 Hz, it s understood that it will be necessary to use ironcore transformers. Hence, in practical drawings the ironcore symbol is omitted, and the above Y transformer would be drawn as shown in Fig. 255.

Painting Code 128 Code Set B In Visual C#.NET Using Barcode creator for .NET framework Control to generate, create USS Code 128 image in VS .NET applications. In Figs. 254 and 255, note that the full generator output (the line voltage) is applied to each of the three connected primary coils. This voltage, after being stepped up by each individual transformer, then becomes the phase voltage on the Yconnected secondary side. Problem 202 Given that there is no external load on the connected generator of Fig. 247, explain why there is no current ow around the closedloop circuit formed by the three generators.

Barcode Creation In VS .NET Using Barcode creation for VS .NET Control to generate, create bar code image in VS .NET applications. Problem 203 (a) In Fig. 248, nd the phase voltage if the line voltage is 3300 volts. (b) Suppose, in Fig. 254, that the transmissionline voltage is required to be 66,000 volts. If each of the three transformers has a turns ratio of 1to12 (primary turns to secondary turns), what value of generator phase voltage is required Painting Barcode In .NET Using Barcode maker for VS .NET Control to generate, create barcode image in VS .NET applications.

Generating UPC Code In Java Using Barcode drawer for Android Control to generate, create UPC Code image in Android applications. EAN13 Generator In Java Using Barcode printer for BIRT Control to generate, create EAN / UCC  13 image in Eclipse BIRT applications. Here we take up the case in which a balanced Yconnected generator feeds a BALANCED " threephase load of Z ohms per phase, taking, rst, the case of a balanced Yconnected load. Let us begin by redrawing Fig. 248, now adding some additional notation, as shown in Fig. 256.

UPC  13 Decoder In C#.NET Using Barcode reader for Visual Studio .NET Control to read, scan read, scan image in .NET applications. It s apparent, by inspection, that the above can be a totally symmetrical, balanced system only if the generator phase voltages are equal to the corresponding voltage drops in the load; that is, only if " " Vna Vn 0 a 0 " " Vnb Vn 0 b 0 " " Vnc Vn 0 c 0 Painting 1D Barcode In VB.NET Using Barcode encoder for .NET framework Control to generate, create Linear image in VS .NET applications. Generating Code 128 Code Set C In Visual Basic .NET Using Barcode creator for Visual Studio .NET Control to generate, create Code128 image in Visual Studio .NET applications. " " " Also, in the gure, the three line currents are denoted by Icc 0 , Iaa 0 , and Ibb 0 as shown. Also note, from direct inspection of the gure, that the three line currents are actually equal to the phase currents (this is true only for a balanced Yconnected load). Since we re dealing with a balanced system, it follows that the line currents (and also the phase currents in this case) all have equal magnitudes; that is " " " jIcc 0 j jIaa 0 j jIbb 0 j IL Ip 437 Next, the POWER, P, produced in the above balanced Yconnected load can be found as follows. First, as before, let Vp be the equal magnitudes of the three phase voltages. Then, since Vp and Ip denote the magnitudes of the rms voltages and currents in each of the CHAPTER 10 Magnetic Coupling. Transformers
three load impedances, it follows (from section 8.5) that the POWER Pp produced in each of the three impedances is equal to Pp Vp Ip cos 438 and thus the TOTAL POWER PT produced in all three impedances in Fig. 256 is equal to PT 3Vp Ip cos 439 where cos is the same power factor of each of the three equal impedances. Or since, by eq. 435, p Vp VL = 3 and also since, Ip IL eq. (439) can also be written as PT p 3VL IL cos 440 which gives the total power produced in the balanced Yconnected system of Fig. 256 in terms of line voltage and line current. Problem 204 " In Fig. 256, suppose the generator phase voltage is 330 volts and Z 15 j9 ohms. Find the total power output of the generator. (Answer: 16,014.03 watts) Problem 205 In problem 204, show that the line currents lag the line voltages by approximately 618. Next, suppose the load in Fig. 256 were deltaconnected instead of Yconnected. In such " a case the situation at the loadend of the line would be as shown in Fig. 257, where VAB , "BC , and VCA denote the three line voltages (as in Fig. 248). Also, let us denote the three V " " " line currents by IA , IB , and IC , as shown.
