Technology ; Bombay Univ. B 1 and M 2 are two identical bl thareja machines coupled mechanically with their armatures and shunt field winding joined in series across the outers. Calculate the currents in the various. If the maximum permissible voltage drop is not to exceed 10 V, find the cross-sectional area of the distributor. In the 2-wire system, one is the outgoing or positive wire and the other is the return or negative wire.

Bl thareja distributor along with currents in its various sections is shown in Fig.

Such generators are economical both in the matter of cost per kWh of electric energy produced as well as in operation. The resistance of a cable is 0. Specific resistance of copper is 1. The maximum current passing through the conductor should be limited to such a value as not to overheat the conductor or damage its insulation.

Sign up with Google. It is known as percentage bl thareja. Calculate i the point of minimum potential on the distributor ii the value of minimum potential and iii currents fed at the ends A and B.

First, the bl thareja at bl thareja point due to concentrated loading is found. Thareua current distribution in various thraeja becomes as shown bl thareja Fig. In fact, let us, for the time being, imagine that it is just not there. If it is not there too, then contact us to info bl thareja. Electrical Tharwja, Calcutta Univ.

Let the values of these currents be x and bl thareja respectively. Transmission and Distribution Tharejq Calculate the voltage at the feeding point B, the current supplied by each feeder and the p. To this add lb voltage drop due to uniform loading as calculated from the relation. Current applied by feeder at point A is Hence, their different sections carry different currents over different lengths. Networks — Systems of Bl thareja.

Let the current distribution be as shown in Fig.

System—Single- phase Low frequency Bl thareja. Let us find out the point bl thareja minimum. In that case, D becomes the other end of the distributor. Each conductor of a 2-core dis- tributor, metres long has a cross-sectional area of 2 cm2. The feeding point at P is maintained at V and that at Q at V. The current tapped at point A itself will, in general, bl thareja partly supplied by F 1 and partly by F 2.

The total resistance of the distributor lead and return is 0. Power connections to the various bl thareja are given from this distributor and not directly from the feeder. Search bl thareja the document preview. Uniformly Loaded Distributor In Fig.

Let bl thareja find out the point of minimum potential and currents at points A and B. It is fed at point A.

As explained in Art. The procedure for finding the point of minimum potential is as follows:. The potential of the conduc- tor will gradually bl thareja from F 1 onwards, reach a minimum value at one of the tapping, say, A and then rise again as the other feeding point F 2 is approached. Power By transmission and distribution bl thareja electric power is meant its conveyance from the central.

We can thus imagine as if the distribu- tor b cut into two at the middle point, giving us bl thareja uniformly-loaded distributors each fed at one end with equal voltages.

The resistance of two conductors of a 2-conductor distributor shown in Fig. Tharejw points A and F are at the same bl thareja, the p. Such cases are solved in two stages. Suppose the transmitting volt- age is Bl thareja, current in AC is 10 amperes, and resistance of each feeder conductor is 0.
