    Abstract: introduction was made to the calculation method of voltage and line loss in medium and low voltage electrical network. Analysis was made to the voltage distribution of typical 35 kV transmission lines and the power loss of 10 kV distribution network. This paper used Newton-Raphson algorithm and the method of equivalent resistance to compute voltage distribution and line loss in a certain region of Shaanxi. In allusion to the factors of line loss, the corresponding loss reduction scheme was proposed. The scheme has reference significance for medium and low voltage electrical network transform.
    Key words: transmission and distribution network; voltage balance; reactive power optimization; line loss; loss reduction
