Low Voltage & High Voltage Earthing Protection – A Case Study at an EFW Plant

In the context of electrical earthing or grounding. Earthing Protection defined as the Protective Earthing of electrical installations at low voltage, i.e. <1,000V AC as described in Electrical Earthing Standards BS 7430.

So, in this case, study. We take a look at a few challenges we came across while designing the HV Earthing and Lightning Protection Systems. For a 9MW Energy from Waste Plant in Europe.

Your Standard Earthing Design – Are They Valid Anymore?

A number of organisations across the UK recommend a standard earthing design when building smaller scale substations. The key driver behind these is one of cost. Nobody wants to pay more than they have to. For an HV connection using a templated approach to meet Earthing Standards compliance kind of makes sense – or does it?

So, the question is – does installing a standard earthing design meet your obligations under the Electricity at Work regulations?

Electrical Earthing Testing in Urban Environments

Electrical earthing testing.  We are asked frequently – How do you test an Earth arrangement in London?

Here’s the scenario.  You are faced with Electrical earthing testing a substation. And that is located right in the middle of a densely built-up area. Also, with hard surfaces everywhere together with congested buried infrastructure in every direction.

So, any lead deployment invariably obstructed by something, e.g. roads, cars, walls, buildings, etc.  And, assuming the leads can be accommodated. An electrical earth test is likely to suffer in-ground noise and interference from the city’s / town’s infrastructure.  Also, not to mention the curious passers-by. Whom would like nothing more than to see you struggle for a laugh by stealing your test leads. When you turn your back.

How We Answer Impossible Questions To Design SAFE Electrical Earthing Systems

Computer modelling for safe electrical earthing systems for Fault, EMI or Lightning Attachments

The use of computing power to check, evaluate or inspect concepts in all walks of life and business, is increasingly common. Whether you forecast the performance of stock and shares or building an Electrical Generation Plant.

For safe electrical earthing systems using engineering computer software such as CDEGS allows us to stress-test designs and systems to evaluate their performance under given conditions.

Electrical Earth Condition Monitoring Vital When You’re Responsible for Keeping Critical Assets Operational

Smart Maintenance using Electrical Earth Condition Monitoring

Electrical Earth Condition Monitoring is vital…

Picture the scene… you’re the person responsible for keeping a multitude of mission critical assets operational and available at all times.  You can’t afford to have any piece of equipment not performing as it was intended.  All decisions you make are usually of the kind that are the career-defining or the career-ending ones.  If things do degrade to the point where they might fail, it’s you that people turn to, at the front-line or shareholders; and either start shouting or asking some really uncomfortable questions, right?
