DC Distribution

DC Distribution:

Booster Generator : A Booster Generator is a D.C. generator whose function is to inject or add certain voltage into a circuit so as to compensate the IR drop in the feeders etc. A Booster Generatorr is essentially a series d.c. gen­erator of large current capacity and is con­nected in series with the feeder whose voltage drop is to be compensated as shown in Fig.13.65. DC Distribution …


DC Distribution Calculation : In addition to the methods of feeding discussed above, a DC Distribution Calculation may have concentrated loading uniform loading both concentrated and uniform loading. The concentrated loads are those which act on particu­lar points of the dis­tributor. A common example of such loads is that tapped off for domestic use. On the other hand, distributed loads are those which act uni­formly on all points of the distributor. Ideally, there are …


Different Types of DC Distributors : Different Types of DC Distributors – In the beginning of the electrical age, electricity was generated as a direct current and voltages were low. The resistance losses in the lines made it impracticable to transmit and distribute power for more than a few localities of the city. With the development of the transformer, a.c. has taken over the load formerly supplied by d.c. Now-a-days, …


Ring Distributor : A distributor arranged to form a closed loop and fed at one or more points is called a ring distributor. Such a distributor starts from one point, makes a loop through the area to be served, and returns to the original point. For the purpose of calculating voltage distribution, the distributor can be considered as consisting of a series of open distributors fed at both ends. The principal …


Three Wire DC Distribution System : The great disadvantage of direct current for general power purposes lies in the fact that its voltage cannot readily be changed, except by the use of rotating machinery, which in most cases is too expen­sive. The problem can be solved to a limited extent by the use of Three Wire DC Distribution System which makes available two voltages viz. V volts between any outer …


Three Wire DC System Balancer Set : Although in a 3-wire d.c. system every effort is made to distribute the various loads equally on both sides of the neutral, yet it is difficult to achieve the exact balance. The result is that some current does flow in the neutral wire and consequently the voltages on the two sides of the neutral do not remain equal to each other. In order …
