AN INVESTIGATION INTO THE CAUSES, EFFECTS AND IMPROVEMENT OF VOLTAGE DROPS ON AN 11 KV FEEDER

Abstract

As technology is advancing the consumptions of power is steadily rising. There are three steps for proper electrification these are Power Generation, Power Transmission and Power Distribution. This three are equally important for proper electrification, without any one of this three the electricity system will be incomplete. Energy losses occur in the process of supplying electricity to consumers due to technical losses. The technical losses are due to energy dissipated in the conductors and equipment used for transmission, transformation, sub-transmission and distribution of power. These technical losses are inherent in a system and can be reduced to an optimum level. This paper presents a study on technical losses in distribution system and analysis of the impact of losses in power sector. Moreover, the impact of different types of transformer and other type of equipment’s connections to the substation and feeder will also be investigated. Keyword-- Feeders, sub-transmission network, voltage drops. The causes and feeder loss of DESCO kallyanpur sub-station of Dhaka has been calculated. This study is done & the calculation shows that the technical loss of total distribution system loss in which 11.28% in 11KV line loss. This loss is reduceable by different kind of method. So how to improve and reduce the loss of feeder, we describe in this paper.
