A Study on the Effect of Ground Resistance on Inductive Interferences nearby 22.9 kV Distribution Lines
Ground resistance is a widely accepted performance index of grounding electrode system. Lower resistance is generally considered to be desirable because of its better grounding performance. Sometimes, however, lower ground resistance may have disadvantages from a certain point of view. Magnetic field generated nearby faulted powerlines is closely related to ground-return currents. Large ground resistance of multi-grounded neutral line can reduce ground-return current and, consequently, mitigates the problem of inducted voltages appearing nearby communication lines. In this paper, groundreturn currents and its relationship to ground resistance was investigated based on EMTP (Electro-Magnetic Transient Program) simulations.
