Understanding Electromagnetic Inference using Finite Element Analysis

EMI using Finite Element Analysis

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 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.

50 Shades Freed – Unleashing CDEGS!

CDEGS earthing plot

During my previous blog, where we explored the analogy of the car when comparing to Earthing Studies using CDEGS – if your project is a high value, critical asset, and/or infrastructure effecting large populations – then this is likely to require a more demanding level of performance in the foundational design data.

50 Shades Darker – CDEGS Myths Busted!

LaFerrari

CDEGS Modelling Software demystified!

It’s interesting how the psychology of the car has found a place in our daily lives.  How many times have you asked or been asked ‘what car do you drive?’ [Read more…] about 50 Shades Darker – CDEGS Myths Busted!

50 Shades of GreyMatters

electricity-pylon

Recently, I received a call from a client in the Nordic region to review an earthing system problem – the client explained they had “… unexplainable noise on their clean earth” and could we help solve it? [Read more…] about 50 Shades of GreyMatters

Electrical Earthing Protection For Data Centres

Electrical Earthing Protection

Electrical Earthing Protection for Data centres barely existed thirty years ago. But, in the past few years, they have become essential to the functioning of virtually every large business. And professional organisation.

Very little commercial or administrative activity can take place if the computers are out of action. So, every minute of data centre downtime can have severe consequences for a firm’s profitability. Also, crucially, its reputation. Therefore, sound Electrical Earthing Protection can help to ensure that frequent but unpredictable events. Such as lightning strikes. And power surges do not cause data loss. As well as, severe and lasting damage to sensitive data centre equipment. Therefore, electrical earthing is a matter of vital importance.
