DEHN is looking forward to participating in the 37th International Conference on Lightning Protection (ICLP) 2024. The prestigious conference in Dresden from 1 to 7 September brings together experts and specialists from all over the world to discuss the latest developments and research results in the field of lightning protection. With a total of nine technical contributions, DEHN helps to create a specialist platform where international scientific and technological experts can exchange ideas and address the challenges of the future together.

The importance of decentralised energy generation through PV systems will continue to increase. Safe operation of these systems is therefore essential for a stable energy supply. However, solar power cannot be generated without an inverter, the central component of a solar power system. But the inverter could be disrupted or even fail completely if, for example, subjected to the force of a lightning strike. Surge arresters (SPDs) for protecting the DC side of inverters are therefore an important component of protection concepts. DEHNguard MP YPV is the new surge protective device from DEHN for protecting photovoltaic systems on residential buildings. This Type 2 DC surge arrester expands the product range with its practical push-in double terminal. As a prewired, modular complete unit for photovoltaic systems, consisting of a base part and plug-in protection modules, it offers advantages for planning, installation and maintenance.

More frequent extreme weather events and increasingly interconnected electronic devices pose a greater risk of damage due to lightning strikes and surges. Appropriate protective measures in compliance with current standards and regulations are required to protect people, buildings, systems, as well as modern energy generation and storage. From 3 to 8 March 2024, DEHN can be found at stand B90 in hall 12.0 where it will be presenting solutions for the new DIN 18014 as well as technologies and products for electrical engineering, home and building automation and safety technology. DEHN will be showcasing protection solutions for industry, PV systems and residential buildings, including refurbishment, renovation and modernisation.

The new wireless inspection camera is part of the DEHNproX product family and enables safe inspections and easy handling with a wireless connection to a smartphone or tablet. This practical inspection camera is used for regular visual inspection and documentation of the condition of electrical systems up to 150 kV / 15 to 60 Hz. It is simple and safe to operate by qualified electricians without the need for special training and can be easily controlled via WiFi using a smartphone or tablet. The voice command feature is especially practical.

A prerequisite for the successful expansion of electromobility is a large-scale networked and intelligent charging infrastructure. Elements such as battery-powered storage, remotely controllable charging stations with integrated energy and load management systems, and charge controllers have one key thing in common: they all contain sensitive electronic components which are highly susceptible to damage caused by lightning and surges. The compact DEHNcube EMOB solutions offer protection for wallbox and vehicle with a charging capacity of 11 to 22 kW and are easily retrofitted in existing systems. 

Pipelines are the lifeline of our industrialised society. Their reliable functioning is essential for many supply and production systems. Increased bundling of transportation and energy routes increases inductive and ohmic interference on pipelines. As a result, voltage can occur on and damage pipelines. This may present a hazard to people, material assets and the environment, often resulting in high repair costs. Interference voltages can be caused, for example, by nearby high-voltage transmission lines and railway lines, but also by earth faults and lightning currents. The screwable earth rod from DEHN is the solution for safe earthing. The very low earth electrode resistances achieved with it reduce the corresponding voltages on the pipelines to a minimum. Interference voltages are safely discharged, thus protecting pipelines and people.

More than 99 percent of German companies are small to medium size enterprises (SMEs). Not only do they account for around half of the country's total economic output. They also employ around 60 percent of the total workforce in Germany. Some of these companies stand out for their exceptional entrepreneurial drive and courageous plans for the future. Every year, the Bavarian State Ministry of Economic Affairs, Regional Development and Energy selects fifty exemplary Bavarian companies under the motto "Bavaria's Best 50" - and DEHN is once again one of this year's award winners.

A failure of sensitive, networked technology, whether in industry, infrastructure or even in residential and office buildings, is unacceptable and often has serious consequences. DEHN, one of the world's leading suppliers of surge protection, lightning protection, earthing and safety equipment, offers protection solutions for industry, photovoltaic systems, e-mobility charging infrastructure, energy storage systems, LED lighting, railway infrastructure or even residential and office buildings, for example – in tailor-made fashion to meet all different requirements. "Mobilising electrification and digitalisation for a sustainable society", is the slogan for this year's ELFACK, one of the most important trade fairs in northern Europe for energy and electrification, which is taking place from 9 to 12 May 2023 in Gothenburg. Accordingly, on the occasion of the first public appearance of DEHN Sverige at stand G00:40, DEHN will show how the challenges described can be solved easily and safely.

Over the past few years few topics have been as intensively discussed as our energy supply. What components should our energy mix have in the future to support the further development and expansion of the various megatrends of our time? Particularly in the recent past, the topic of hydrogen has become increasingly prominent, but only a few players are currently venturing into the subject. A first coordinated initiative is the " Hydrogen Center Bavaria (H2.B) ", which links partners from industry, science and politics. DEHN has been part of the alliance since the beginning of 2023. For regardless of whether it is a matter of producing or transporting "green hydrogen", comprehensive protection against lightning strikes and surges is essential.

Smart technological solutions for residential and functional buildings, and networked systems in infrastructure and industry, are currently the state of the art. Maximum availability is a prerequisite here. Malfunctions with unscheduled downtimes can quickly cause significant additional work associated with extremely high costs. The reliability and protection of sensitive systems is therefore of the highest priority. Comprehensive lightning and surge protection is an essential component in rendering installations and systems safer and more reliable, and thus more efficient. At this year’s Light + Building, from 2 to 6 October, DEHN is presenting pioneering protection solutions for a wide variety of fields – be it for residential buildings, industrial buildings, data centres or e-mobility.

Advancing digitalisation demands an ever faster supply of data.  High transmission volumes and ever improving bandwidths are a prerequisite. Structured cabling is an important component of today's network topology for information and data technology. In this context, safety is a multifaceted topic, in which lightning current and surge arresters play an important role. The new DEHNpatch DPA CL8 EA 4PPOE arrester is designed for use in a switchgear cabinet or data distributor and can handle data rates of up to 10 GBit/s.  With Power over Ethernet (up to 4PPoE with a power transmission of up to 100 W), class EA transmission standard (max. 500 MHz), status indication and the possibility of remote signalling, the DEHNpatch is equipped for modern applications. Available bandwidths can be maxxed out while undisrupted data transmission can be ensured.

DEHN and Max Bögl collaborate on a wind tower project

How to prevent damage to a wind turbine as best as possible if lightning strikes the exposed tower? This was the question posed to simulation experts from DEHN along with the Max Bögl Group in a project. Now both companies are benefitting from the results.

Equipotential bonding is essential; particularly in potentially explosive areas. It eliminates differences in potential, thus preventing dangerous touch voltages and sparking. In order to achieve this, all external, conductive system parts and installations that could cause dangerous potential differences must be connected to the main earthing busbar.

In just 4 standard DIN modules, the compact combined arrester, type 1+2+3, protects against transient overvoltages in low-voltage switchgear and controlgear assemblies. Small width and a compact single module that saves you time during installation and maintenance.
