    EMI mitigation for panel builders

    When designing modern power systems one of the main challenges faced by panel builders is finding the right components to build a complete system. The number of possible component options and alternatives on the market is so high that a key differentiator needs to be found to quickly locate best fit products.

    Hitting the power quality “bull’s eye”

    For experienced electrical engineers, warning signs that things aren’t running smoothly can be fairly obvious. What’s sometimes less clear is choosing the best solution, particularly in more complex scenarios where devices like variable speed drives (VSDs) are used. Here, Steve Hughes, Managing Director of REO UK, explores some electrical weak points that can be found on almost any production line.

    Solving the data centre dichotomy

    By 2020, there will be 40 times more bytes of data than there are stars in the observable universe. The question is, are our digital-first lifestyles really creating an environmental villain, or could data centres be the answer to our energy crisis by helping to drive the use of renewables and take pressure off our reliance on carbon-energy?

    Why low-voltage assemblies must comply with BS EN 61439

    Low-voltage switchgear and controlgear assemblies are at the heart of most electricity distribution networks. Few assemblies cause any problems throughout their life, in part because many never, if ever, are fully loaded or subject to a design limit occurrence. However, if issues arise it can be many years after the initial installation and if they do arise, the consequences can be severe.
