The transmission line carries power from the center of the generation to the load center through a high-voltage airway (SUTT) or an extra high-voltage airway (SUTET). In the transmission line there are loss - loss and loss - loss of power caused by several factors such as corona and conductor resistance, resulting in voltage drop and decreasing conductor capacity. If one of the conductor networks is extinguished then the other delivery network will support loads that are not suited to the carrying capacity. Based on this, then conducted an analysis of the loss of power that occurs, so that later useful in knowing the transmission line transmission system. Transmission lines in Tebing Tinggi - Kuala Tanjung use ACSR (Alluminium Conductor Steel Reinforced) consisting of a mixture of aluminum and steel with a diameter of 240 mm2. With ACSR conductor diameter still possible for power losses of great value. For that reason, PT. PLN (Persero) UPT Pematang Siantar will recondition conductor using ACCC conductor which has twice carrying current carrying from ACSR to decrease power losses at Tebing Tinggi ? Kuala Tanjung. In the calculation of these power loss calculations, it can be concluded that the reconductoring of ACSR conductors into ACCC can increase transmission line efficiency up to 1.35% and increase the carrying capacity of current doubled current in the conductor and reduce the power loss from 4.78 megawatts to 3.87 megawatts.} }
