ANÁLISIS DEL EFECTO DE LA IMPEDANCIA DEL CAMINO DE RETORNO ANTE FALLAS MONOFÁSICAS EN LOS RELÉS DE …
This alternative considers the analysis of the fault and return path impedances. The proposed method is tested in a 500kV, 100 km length power line, where the errors are lower than 5% even in case of fault resistance of 20Ω and return path resistance of 0,2Ω/km. KEYWORDS: Fault distance, distance relays, fault resistance, return path resistance.
