This thesis has been written to improve the electricity situation in general as well as the electri city distribution system in particular, in Pakistan. Jn the wake of the com1try's serious short.ages of electric:ity, this thesis points to the .importance of control.ling distribution losses, which consist of technical and non - t(H:hnical losses. Th ese losses .l ead to a reduc tion of electr.ic:H.y supply which mal<es load sh e ddi.ng quite hi gh. In order t o reduce technical lossc-:!s , a r ehabilitation approach is established in this stu dy. This rehabilitation approach shows how much conservation is possH>.l e by considering fo-ur· options. 'J'l1ese in clu de: Repladng a highly loaded, low capacity transformer by larger one, Replacing t he transformer a nd 1·econcluctoring, Shifting t he transformer to its optimum posit.ion a nd Splitting the existing circuit into two seperate circuits. The main purpose of rehabilitation of the existing circuit ls to a chieve WAPDA's prescribed standard for transfom1er loading and maxhnum voltage drop. Als o for the n on - t echnical losses, a detailed description ls glven t o sh ow th e different. r eason s for t.h es<~ losses.Policy options are then described for t h e redu ct.ion of non - t.eclrnical losses. This thesis also discusses the major role that electricity consumers can play in conservin g en er gy th rough the effic:i ent use of el ectr.ic:al appliances. The meas ures and policy opt.ion s for effecient use of electrical appliances for the sake of conserving en ergy are also cl esc:ri becl.
