In this article, we will present one-ended impedance-based fault location methods commonly used in the industry. Basic principles will be laid-out and a step-by-step calculation will be presented. Why? It is because most numerical relays can measure voltages and currents. In. When the fault occurs at point X in the protected zone then the voltage drops while current increases. Calculate the multiple of Pick Up value for the Isc corresponding to the instantaneous setting. These include the transformation of. Real-Time Impedance Calculation The tool starts with the load impedance using voltages and currents under load according to the formula: Where: Users can visualize the impact of changes to these parameters on the impedance plane.
