“…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.…”

“…Indeed, the unknown fault current I F is necessary for the calculation. Applying Kirchhoff's Voltage Law (KVL) to the system from the point of view of side A results in (1), which is the base to extract the fault reactance and resistance:…”

“…Replacing the fault current by the product of these two quantities in (1), and multiplying by the conjugated product of the fault impedance and phase current Z Fault * I A,Ph * , the voltage drop on the fault impedance can be eliminated and the fault resistance can be extracted:…”

“…As considerações necessárias à referida particularização são relatados em Takagi et al (1982) e, tal como feito em Takagi et al (1981), o método se fundamenta sobre o conjunto de equações que segue. Dessa forma, a corrente de falta I F fora expressa por meio do seguinte relacionamento: …”

“…Então, isolando-se o termo Takagi et al (1982), a localização de faltas para sistemas trifásicos pode ser particularizada para as faltas fase-terra da seguinte maneira: Em função da existência de cargas intermediárias ao longo de um alimentador de distribuição e da elevada resistência da linha, as quedas de tensão provocadas pela falta podem se tornar significativas e com isso modificar a corrente consumida por cada carga do circuito, se estas forem modeladas como impedância ou potência constante. Assim, é equivocada a hipótese de que a corrente de carga durante a falta (I La ) pode ser assumida como sendo seu valor pré-falta (I Sa ).…”
