Influence analysis of calculated horizontally layered soil parameters on grounding parameters

open access: yesHigh Voltage, Volume 8, Issue 2, Page 421-430, April 2023., 2023
Abstract Calculated parameters (soil layer resistivity, soil layer thickness, and the number of soil layers) of horizontally layered soil are usually obtained based on the measured apparent resistivity under different measurement distances, which are significant for the design, operation, and maintenance of grounding grids.

A novel approach to touch voltage risk assessment for gas pipelines in shared transmission corridors

open access: yesIET Science, Measurement &Technology, Volume 17, Issue 1, Page 27-36, January 2023., 2023
Abstract Touch voltages are more likely to appear on long‐distance pipelines that lie in shared corridors with transmission lines. The touch voltage level varies with soil resistivity and can become hazardous while maintenance is being undertaken, necessitating risk assessment.
