“…Single-ended fault location [1][2][3][4][5][6][7][8][9][10] uses only one end of the line current and voltage information to determine the fault distance.It does not need the channel to transmit opposite side data, so it is not limited by communication technology. Fault location algorithm using single-ended data can be divided into three categories.The first is the method for solving differential equations.The second uses power frequency electrical quantities to locate fault position.The third finds the fault location according to the characteristics of the voltage distribution along the line under fault conditions.Double-ended fault location [11][12][13][14][15][16][17] has sufficient or redundant location equations.…”

“…A primeira dessas aproximações impõe que R F seja puramente resistiva, não possuindo, portanto, parcela imaginária. A segunda aproximação, pontuada por Takagi et al (1981), estabelece que a relação K(x) também é um valor real. Essa consideração é válida supondo-se uma linha de transmissão sem perdas, bem como tendo impedâncias equivalentes para as fontes como sendo puramente indutivas.…”
