Operation & Maintenance of 33/11 Kv Substation of Dhaka Palli Bidyut Samity-1

Abstract

As technology is advancing the consumptions of power is steadily rising. There are three steps for proper electrification these are:- 1.1 Electric Power generation. 1.2 Electric Power Transmission. iii) Electric Power Distribution. This three are equally important for proper electrification, without any one of this three the electricity system will be incomplete. Power Grid Company ltd is the BPDB (Bangladesh Power Development Board) wound company which is the only authorized company for the Electric Power Transmission sector in Bangladesh. Rural Electrification Board (REB) has many sub- stations all over the country which are connected through the distribution line, these stations are called sub-station.
