How can tidal power realise its potential?
The UK Government estimates that tidal energy could meet around 20% of the country’s electricity demands. Despite this fortunate position, uptake of tidal power has been slow. How should we encourage the development of this promising resource? Here, David Atkins, Projects Director at Cressall, has explored how technology can guarantee the future of tidal power.
Is the end of rail franchising enough?
In September 2020, after 24 years, the UK Government announced the end of rail franchising. The goal is to move to a simpler and more effective operatingmodel that improves the transport experience for passengers. In parallel with the transition to the new rail system, what more can be done to reform our railways? Here David Atkins, Projects Director of Cressall, looks at the system change and some of the technologies that are improving rail...
Cressall improves efficiency of mesh resistor element
Power resistor manufacturer, Cressall, has trialled a new configuration for its expanded mesh resistor element. The new, 'Omega' shaping of the resistor elements will provide customers with an improved resistor design and better displacement of the mesh elements.
Eliminate modern power headaches before they occur
Health advisors always reiterate that prevention is better than cure. Take care of yourself, and preventable problems are less likely to arise. Engineers dealing with power-reliant processes should adopt a similar approach to power protection. In this article, Joshua Piccaver, Electrical Design Engineer at Cressall, takes a look at the areas of industry that require power protection.
Electrifying the UK heavy vehicle market
The Department for Transport Statistics reports that there were 501,500 heavy goods vehicles licenced in the UK in 2019, but only 400 of these were battery electric powered. With heavy goods vehicles being a significant contributor of carbon emissions, will we see an increase in electric power? Here, Joshua Piccaver, Electrical Design Engineer at Cressall Resistors, has explored the potential of electrifying the UK heavy vehicle market.
Power resistors aren’t only for industrial plants
While many of us probably have a vague idea of a resistor’s function, you most likely think of them as part of an industrial plant or large-scale operation. In reality, you’re never too far away from this essential power component. Here, Mark Barfield, Engineering and R&D Manager at Cressall Resistors, explores the range of applications for industrial power resistors.
Is the UK’s coal-free hiatus here to stay?
Britain passed a significant landmark in June 2020, as the nation went coal-free for two months. A decade ago, around 40% of the UK’s electricity came from coal and, while the recent plummet in demand accounts for some of the success, it isn’t the full story
How to choose a resistor for your automotive application
The electric car boom is upon us. However, the technology behind the movement must continue to be refined to perfect its use in commercial vehicles. Here Simone Bruckner, Managing Director of power resistor manufacturer, Cressall Resistors explains what manufacturers must consider when choosing power resistors for electric vehicles.
Cleaning up rail power
A British solar power company is developing a technology that could use solar energy to power the UK’s railways and thus be key for cleaning up rail power.
(Re)designing resistors with computational fluid dynamics
Here, Damiano Natali, research and development engineer at power resistor manufacturer Cressall, explains how Computational Fluid Dynamics (CFD) improves product designs that have stayed much the same for decades.
Key considerations when designing electrical enclosures
There’s a lot to be learned from the famous fable, The Three Little Pigs. While the tale teaches us to stay wary of menacing wolves, it also reminds us of the importance of a sturdy home. Electrical equipment requires robust protection and a durable electrical enclosure in order to reassure its saftey.
Energy-efficient braking crucial to autonomous vehicles
When a self-driving Uber crash led to a fatality in 2018, to many, it seemed that the autonomous vehicle revolution was over before it had chance to gather speed. If autonomous vehicles are to make it onto our driveways, energy-efficient braking systems will be crucial to minimising accidentse
Electrifying the future of the vehicle market
By 2040, the government’s proposed ‘Road to Zero’ emissions plan will require each new car sold in the UK to have an electric driving range of at least 50 miles. With electric vehicle capabilities in the midst of switching from an environmentally kinder preference to a mandatory requirement, the vehicle market will have to electrify more than just commercial vehicles.
Dynamic braking resistors and elevator efficiency
As cities continue to grow, it seems like the only way is up. Increasing urbanisation in recent decades has led construction companies to build upwards, with the construction of over 500 high-rise towers in the pipeline for the city of London alone.
Electrifying the track!
Faced with growing pressure to reduce carbon emissions, European countries are increasingly making moves to power trains with electricity instead of diesel. In the UK, however, progress has often appeared hampered. Simone Bruckner, Managing Director at Cressall Resistors, looks at why the electrification of rail transport should be prioritised.
Surge suppressors for extra power protection
Compact and easy to install, ZORC suppressors can halve the magnitude of steep wave-front surges by providing a matched cable terminating impedance under transient conditions, eliminating any refraction of the surges. As well as protecting motors, generators and transformers throughout their service life, the suppressors also help prevent costly equipment downtime that could occur as a result of insulation failure.
Busting electric vehicle myths
Following a surprise break into the EV market, Dyson’s £2bn project came to the end of the road in October 2019. As the famed maker of vacuum cleaners and hair dryers failed to find a way to make its project commercially viable, is the EV hype fizzling out? Simone Bruckner, Managing Director of Cressall Resistors, busts some of the myths in EV uptake.
Down to the wire: A resistor’s role in laying cables
While we may associate data with being up in the clouds, it’s very much in the ocean too. Beneath our seas lie thousands of cables, tasked with carrying the world’s internet traffic. These cables form a vital communications network - and the world would seem like a much bigger place without them. What is less often considered is how these cables made it to the sea floor in the first place. Simone Bruckner, Managing Director at Cr...
The impact of the latest emissions regulations on generators
Air pollution is now the biggest environmental risk to public health in the UK. As unregulated medium sized combustion plants (MCPs) and generators are a known source of significant air pollution, addressing their environmental impact is crucial. Here, Andrew Keith, product development director at power resistor manufacturer Cressall Resistors, discusses the changes to emissions regulations and what they mean for power maintenance.
What’s fuelling our data?
In 2018, Chinese data centres produced 99 million tonnes of carbon dioxide (CO2) - generating the equivalent environmental footprint of around 21 million cars. With global data traffic more than doubling every four years, it’s no surprise that the environmental impact of data centres is coming under scrutiny. Here, Simone Bruckner, Managing Director of Cressall Resistors, investigates the efficiency of our data centres.
