One-end impedance-based fault location algorithms
6.1. Introduction
6.2. Fault location based on impedance measurement
These methods are simple and economical but their accuracy is influenced by factors like fault resistance, load flow, and line parameter inaccuracies.
One-end impedance-based methods estimate fault location using voltage and current measurements at a single terminal of the transmission line.
