In most of case Distribution Transformers are not located centrally with respect to consumers.Consequently, the farthest consumers obtain an extremity low voltage even though a good voltage levels maintained at the transformers secondary. (The reason for the line losses increasing as a result of decreased voltage at the consumers end therefore in order to reduce the voltage drop in the line to the farthest consumers, the distribution transformer should be located at the load center to keep voltage drop within permissible limits.)In most LT distribution circuits normally the Power Factor ranges from 0.65 to 0.75.
Similarly, balancing load among distribution feeders will also lower losses assuming similar conductor resistance.
This may require installing additional switches between feeders to allow for appropriate load transfer.
Thus, line losses owing to the poor PF can be reduced by improving the Power Factor.
This can be done by application of shunt capacitors.
Bifurcation of feeders according to Voltage regulation and Load.
Power consumption of customer varies throughout the day and over seasons.
Feeder phase unbalance may vary during the day and with different seasons.
Feeders are usually considered “balanced” when phase current magnitudes are within 10.
Thus the primary and secondary distributions lines in rural areas are largely radial laid usually extend over long distances.Tags: Adult Dating, affair dating, sex dating
