Abstract :
One of the problems in the electric power system is the change or decrease in voltage that often occurs in the supply of electricity. To anticipate the varying output voltage, the main transformer of the new reefestuary is equipped with On Load tap changer , acting on each load change and the primary side voltage so as to keep the desired voltage constant. Large tapping voltage OLTC transformer 1,25% of nominal voltage. At the tap position 11 with the ratio 7,312:1 and the highest primary side 149 kV , the secondary side of 20,102 kV as well as in the position state tap 10 with the ratio 7,403:1 and highest primary side is 154 kV, the secondary side is 21,8 kV. When the load increases, the voltage regulator will increase the voltage by adjusting the ;lead side transformer voltage, to overcome the voltage drop of the secondary side of the transformer.
