Comparación De Dos Métodos Para Localización De Fallas Monofásicas Considerando La Resistividad Del Terreno (original) (raw)

This paper presents a comparison of two methods for locating faults, considering the influence of the ground resistivity and the fault resistance. The methods are the proposed by a commercial software developer and one of the classic impedance based methods. Tests were performed using three different ground resistivity models, obtained from field measurements. According to the results in a 34kV power distribution system, the performance of the impedance based fault locator is better than the obtained using the commercial software. Additionally, the soil resistivity models which best represent the real systems are those which give better results in fault location.
