Welcome LPI's comprehensive, user friendly, online Earthing Calculator. Available in both Chinese and English, this calculator allows you to estimate earth system resistance based on IEEE and other international earthing/grounding standards. Working left to right, you select the configuration of your earthing system, then edit the dimensions and other parameters. Results are given for the theoretical best-case scenario (as per the standard) as well as likely real-world values as typically seen in the field.
