Electrical resistors for power lines are used worldwide as Neutral Earthing Resistors short-circuit current reduction in grids, and also Filtering combination with capacitors inductances. The manufacturers of such must certificate that they withstand the mechanical thermal stresses imposed by external loads, accordance IEC 62001 standard. Although this certification can be achieved means testin...

In this contribution, measurement data of phase, neutral, and ground currents from real low voltage (LV) feeders in Germany is presented analyzed. The obtained used to review evaluate common modeling approaches for LV systems. An alternative approach detailed cable modeling, which allows the consideration typical German earthing conditions asymmetrical design, proposed. Further, analytical calc...
