Grounding System Adequacy of HV/MV Substations in Areas With Reduced Accessibility [PDF]
, 2015 The adequacy of grounding systems has to be verified periodically in the operational time. With urban development and buildings growth adjacent to power systems as HV/MV substations, it is very rare to have area around with sufficient accessibility for ...

Simplified conservative testing method of touch and step voltages by multiple auxiliary electrodes at reduced distance [PDF]
, 2015 Grounding systems (GSs) must be tested periodically in order to maintain the touch voltage (TV) and step voltage (SV) below a safe value in all of the zones of the installation.

An equivalent circuit for the evaluation of cross-country fault currents in medium voltage (MV) distribution networks [PDF]
, 2018 A Cross-Country Fault (CCF) is the simultaneous occurrence of a couple of Line-to-Ground Faults (LGFs), affecting different phases of same feeder or of two distinct ones, at different fault locations.

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:

The treatment of thin wire and coaxial structures in lossless and lossy media in FDTD by the modification of assigned material parameters [PDF]
, 2006 It has been shown recently that the use of modified assigned material parameters (MAMPs) within the finite-difference time-domain (FDTD) method provides a systematic, readily extensible, accurate, and efficient approach to the electromagnetic analysis of
