Understanding Electromagnetic Inference using Finite Element Analysis

Finite element analysis (FEA) is a computerized method for predicting how a product reacts to real-world forces, energies, vibration, heat, fluid flow, and other physical effects.

Finite element analysis shows how something will perform when stressed, whether it will break, wear out, or work the way it was designed BEFORE it is created, installed or built in the ‘real’ world.

It is called analysis, but in the product development process, it is used to predict what is going to happen when the product is used.

Soil Resistivity Testing in the Wet – Ninja Tricks to Help You Spot the Enemy

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 flow chart) This is chiefly because all these type of systems are connected to earth and rely on the quality of this interface.  Therefore, understanding the soil resistivity and what the representative ‘Soil Model’ will look like is without doubt the single most important foundation to all subsequent safety calculations.

What is Soil Resistivity Testing & Why is it Important to Safe Electrical Earthing Design

What is Soil Resistivity?

Soil resistivity is a measure of how much the soil resists the flow of electricity. It is a critical factor in design of systems that rely on passing current through the Earth’s surface. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the electrical earthing system in an electrical substation, or for lightning conductors.

Electrical Earthing System Design Separation

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 System Design Separation.
