ac dc transmission

Abstract : Seminar The transfer of power from the bulk power all the way for domestic, commercial and industrial consumers is mainly due to high voltage alternating current (AC) transmission and distribution, and a number transformations to reduce power losses and minimizing costs. Applied voltage levels values.AC standard system used for transmission of bulk power instead of DC (direct current) because of its ability to translate the voltage levels using a transformer. The voltage transformation follows Faraday s law, which states that the emf induced in a circuit is directly proportional to the rate of change of magnetic flux through circuit.Note at a higher voltage, current, thus reducing the drop voltage and line loss also reduced.Ability to transform voltage and power flow in two opposite directions (bidirectional communication) is the only major advantage of the AC system on the DC system.
