Earthing - a python library for earthing network design - released

   I am happy to announce the release of Earthing a python library for the design of electrical earthing networks. Currently only homogeneous earth is supported. It should be possible in the future to extent this to include two layer model using imaging techniques. Accuracy of the model needs to be compared against other commercial models for further improvements. Features Earth grid design as per IEEE 80/ ENA_ER_S34 Numerical earth network calculations using using boundary descretisation method. Evaluation of earth resistance of various earth electrode geometries. 3D plotting of electrode geometry used for design. 3D plotting of current density distribution for the earth network. 2D/3D plotting of surface potential distribution. Ploting and evaluation of mesh and step potentials.   Usage Package is available on PyPI for installation ( https://pypi.org/project/earthing ). Use pip install earthing to install. Program source includes detailed usage instructions for various funct
