Soil resistivity measurement is usually performed during the substation design stage. The ground grid impedance measurement (with step and touch voltages) is performed regularly during periodical maintenance. However, those tests are not effective in detecting the grid connections issues that affect its ...
Abstract: For ensuring the safety of persons and equipment in substation, ground potential rise (GPR) should be within the acceptable limits, IEEE Standard 80-2013 is widely accepted guide for substation grounding system design. This review papers deals with the various grounding system parameters, ...
Revision Standard - Active - Draft. Direction and methods for qualifying permanent connections used for substation grounding are provided in this standard. This standard particularly addresses the connection used within the grid system, the connection used to join ground leads to the grid system, and...
