Impact of climatic variations on seasonal changes of earthing resistance [PDF]
E3S Web of ConferencesSeasonal soil-moisture flux causes time-varying soil resistivity and earthing resistance, which can compromise the safety of power-system earthing installations. Using representative sites in South Africa and Nigeria under comparable climates, this paper

Detection and Location of Earth Fault in MV Feeders Using Screen Earthing Current Measurements
Energies, 2020 The paper analyzes the utilization of cable screen currents for earth fault identification and location. Attention is paid on cable and mixed feeders—cable and overhead lines. The principle of operation is based on utilization of 3 criterion values:

Earth system economics: a biophysical approach to the human component of the Earth system [PDF]
Earth System Dynamics, 2020 Abstract. The study of humans has largely been carried out in isolation from the study of the non-human Earth system. This isolation has encouraged the development of incompatible philosophical, aspirational, and methodological approaches that have proven very difficult to integrate with those used for the non-human remainder of the Earth system. Here,
