Finite element analysis (FEA) is a numerical method for solving problems in engineering and applied sciences. It is used to analyze and predict the behavior of complex systems. Such as structures, machines, and electronic devices, under a wide range of conditions (i.e. forces, energies, vibration, heat, fluid flow, and other physical effects). Finite element analysis […]
Soil Resistivity Testing in the wet particularly saturated ground. Has the potential for many problems. Here are some ninja tricks to help you spot the enemy lurking in the damp… Soil Resistivity Testing is the absolute starting point for pretty much everything to do with design for Earthing, grounding and lightning protection. (click link to […]
What is Soil Resistivity? Soil resistivity is a measure of how much the soil resists the flow of electricity. Soil Resistivity Testing is determining that measure. Therefore, is a critical factor in the design of systems that rely on passing current through the Earth’s surface. An understanding of the soil resistivity and how it varies […]
During a recent training event held by SES Technologies for CDEGS (Current Distribution, Electromagnetic Fields, Grounding and Soil Structure Analysis). A finite element analysis software suite for Electrical Earthing System Design, a number of issues were discussed. But one that crops up time and time again in the UK was that old chestnut in Electrical Earthing […]
Earth Testing – We’re frequently asked by Critical Asset owners – “Do we really have to physically test our Electrical Earthing System?”
Code of practice changes for earthing above 1kV for developing energy facilities have identified its best to model energy using specialised CDEGS software.
