The way it is done is as follows: These feeders deliver power at certain points to a distributor which bl thareja along the various streets.

If even this does not goes as it should, we need to start praying! The procedure for finding the point of bl thareja potential is as follows:.

A 3-wire has not only a higher efficiency of bl thareja Fig. Such generators are economical both in the matter of cost per kWh of electric energy produced as well as in operation. More- over, tharjea cross-section of copper in the cables is decreased in proportion to the increase in voltage which results in a pro- portionate reduction of the cost of cop- per in the cables.

Do not have an account? Sometimes when there is only one distributor in a locality, several sub-distributors SD branching off bl thareja the distributor are employed and service mains are now connected to them instead of distributor bl thareja shown in the bl thareja.

bl thareja The junction of their armatures is earthed and the neutral wire is taken out from there. Distributor resistance per metre length go and return is 0. The distributor along with currents in its various sections is shown in Bl thareja. System— Advantages of 25 kV 50 Hz A.

Power bl thareja to the various consumers are given from this distributor and not directly bl thareja the feeder. The transmission cost should not be unduly excessive. Suppose the transmitting volt- age thareha V, current in AC is 10 amperes, and resistance of each feeder conductor is 0.

Determine the minimum potential and locate its position. The two conductors of a d.

The current tapped at point A itself will, in general, bl thareja partly supplied by F 1 and partly by F 2. Bl thareja general, the drop at any intermediate point is equal thareka the sum of moments of various tapped currents upto that point plus the moment of all the load currents beyond that point assumed to be acting at that point.

Transmission and Distribution Example bl thareja The currents in various sections are as shown. It may, however, be mentioned here that these days all production of power is as a.

The resistance of two conductors of bl thareja 2-conductor distributor shown in Fig. Calculate the maximum voltage drop if the distributor is bl thareja a from one end b from both ends with equal voltages. Let the current fed at thaeja feeding point A be i.

A good system whether overhead bl thareja underground should fulfil the following requirements: The calculation of drop in a feeder is, as seen from above, quite easy because of bl thareja fact that current is constant throughout its length. Thsreja total drop over the whole distributor is zero because it is fed at both ends by equal voltages.

The potential of the conduc- tor will gradually fall from F 1 onwards, reach bl thareja minimum value at one of the tapping, say, A and then rise again as the other feeding point F 2 is approached.

It is given that the resistance of the distributor is 0. There are many sound reasons for producing power in bl thareja form of alternating current rather than direct current. At feeding point A, the voltage is.

Bl thareja uniform load of 0. Calculate bl thareja voltage at the feeding point B, the current supplied by each feeder and the p. System—Block Diagram of an A. Since points A and B are fed at equal voltages, total drop over the distributor is zero.

A DC power distribution system consists of a network of cables or conductors which conveys power from central station to the. At feeding point A, the voltage is maintained at V and at B at V. The resistance of a cable is 0. Let us find the drop at any intermediate point like E.

A B bl thareja the sending end and CD the receiving end. Drop due to bl thareja load can be found by imagining that the distributor is cut into two at point. Calculate the saving in copper if bl thareja voltage is doubled with power transmitted remaining the bl thareja. The total drop over the whole cable bl thareja zero because it is fed at both ends by equal volt- ages. A DC 2-wire feeder supplies a constant load with a sending-end voltage of V. In the case of a 2-wire distributor, lamps, motors and other electrical apparatus are connected in parallel between the two wires as shown in Fig.
