Design and Analysis of Frequency-Dependent Dynamic Soil Properties Based Safe Economical Robust Earthing System

The safety, reliability, and resilience of industrial equipment, including drives, Power Electronic Systems (PES), and Distributed Control Systems (DCS), are contingent upon their level of protection. Essential requirements for this sensitive equipment include managing Electro-Magnetic Interference (EMI) and ensuring power quality. Inadequate potential equalization can result in failures or malfunctions of controller cards and internal boards within power electronic devices and distributed control systems. This research offers valuable perspectives obtained from tackling a major challenge within the industry. The research led to the development of a safe, cost-effective, and robust earthing system (SERES) that employs frequency-dependent dynamic soil properties (FDDSP), while also taking into account constraints such as spacing factor (SF) and zone of influence (ZoI). The proposed extension work examines the case study across various seasons and conditions at the test site, emphasizing the performance of the proposed design under dynamic circumstances and evaluating the system’s efficacy through a new SERES model based on impedance parameters.
