Update to the VDE AR N 4100 rules
In this expert discussion, Andreas Habermehl (Managing Director of Technology and Vocational Training at ZVEH), Karsten Pielotek (EWE NETZ GmbH) and Josef Birkl (Senior Engineering Specialist for Standards at DEHN SE) discuss the challenges of the energy revolution in existing buildings and potential solutions. Their focus will be the new VDE-AR-N 4100 rules.
DEHNshield ZP – a revolution at the meter mounting board
DEHN set new standards in surge protection with the DEHNventil ZP, which led to the development of the first DEHNshield ZP in 2016. We demonstrate how state-of-the-art functionality is opening up new fields of application and continuing the success story.
The life-saving TOP principle
Electrical installations carry enormous risks, and small mistakes can have fatal consequences. We present a compact, easy-to-understand guide to practical measures that you can take today – not just to meet regulatory requirements, but to save lives.
What tradespeople really need to know
Whether it's the 10-metre rule, needing to retrofit surge protective devices or old arresters, or complying with standards for new builds and existing structures, this presentation gives practical advice on avoiding typical pitfalls – with compact and flexible solutions for protecting wallboxes, heat pumps and other components of modern homes.
How chatbots are changing electrical engineering
Artificial intelligence has long been part of the everyday work of planning engineers, technicians, dealers and customers. This keynote outlines the innovative applications of AI in electrical engineering – from initial specific use cases to ideas for the future.
Product carbon footprint – a new quality feature for products?
A product's carbon footprint measures the greenhouse gas emissions caused by a product or product group throughout its life cycle, from raw material extraction to disposal. This creates transparency in complex supply chains, enables informed climate strategies at product level and strengthens companies' position in sustainability reports, tenders and business partnerships.
