Substation Grounding Grid Diagnosis Applying Optimization Techniques Based on Measurements and Field Tests

Considering urban substations ground grid diagnosis, some real-physical constraints result in measurement process challenges: 1) limited length between electrodes used to measure the equivalent impedance of the grounding system; 2) to determine the current that flows from ground grid conductors to t...
