Design and Analysis of Grounding Grid Performance Using ETAP 16.0.0 Software

Abstract

This paper gives the different grounding mat design modifications and the impact on the design parameters of these modifications. Different modifications in different cases like case 1: grounding mat design without earth electrodes, case 2: grounding mat design with the electrodes at the corner of mat, case 3: grounding mat design with compression ratio without earth electrode, and case 4: grounding mat design with compression ratio and earth electrodes have been applied with the application of ETAP 16.0.0 version software. The primary framework of the grounding mat solidly depends upon, \( R_{g} \), \( V_{\text{touch}} \), \( V_{\text{step}} \), and ground potential rise (GPR). These quantities are of great concern for safety of any grounding system. Here, our main concern is to minimize the design quantities by inserting electrodes and by changing the compression ratio to meet the standard safety regulations annunciated in various guidelines and standards. Here, in this paper, homogeneous soil model is considered for designing the grounding mat.
