Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations< may be hydro electric, thermal or atomic. Depending upon the availability of resources these stations are constructed different places. These places may not be nearer to load centers where the actual consumption of power takes place. So it is necessary to transmit these huge power blocks from generating station to their load c ....etc

ELECTRICAL ENERGY LOSS IN RURAL DISTRIBUTION
FEEDERS- A CASE STUDY



ABSTRACT

This paper presents the analysis of electrical energy loss in rural distribution feeders. Eastern Power Distribution Corporation Limited, APEPDCL of Andhra Pradesh State in India has been implementing some methods to reduce technical losses on rural distribution feeders. Statistical Data of two years on 80 rural distribution feeders of Visakhapatnam district has been analyzed and the results were presented. Field survey has been ....etc

SUB-STATION EQUIPMENTS & ITS FUNCTIONS
Lightening Arrester
Lightening arrestors are the instrument that are used in the incoming feeders so that to prevent the high voltage entering the main station. This high voltage is very dangerous to the instruments used in the substation. Even the instruments are very costly, so to prevent any damage lightening arrestors are used. The lightening arrestors do not let the lightening to fall on the station. If some lightening occurs the arrestors pull the lightening and ground it to the earth. In any subst ....etc

Abstract:
This paper presents a new methodology for enhancing the distribution system performance by minimizing both technical and non technical losses. Most of the utility companies in developing countries are victims of major revenue losses due to technical and non technical energy losses. The non technical losses are like electricity theft, unauthorized connections, irregular billing and the technical losses are I2R power losses. These losses affect the quality of supply in terms of voltage magnitude, and more tariffs imposed on genuine cus ....etc
