WindEnergy Hamburg: DEHN unveils new cloud solution to improve the availability of wind turbines
Lightning events are among the key external factors affecting the operational reliability of wind turbines. In order to assess their impact reliably and plan maintenance measures in line with requirements, operators need robust data and the ability to analyse it quickly. At WindEnergy Hamburg, DEHN will present DEHNsphere, a new digital platform that provides transparency regarding lightning events and makes it easier to assess them. It uses measured data from the DEHNdetect lightning current measurement system, which records lightning events on the wind turbine itself. Lightning strikes can have significant impair the availability and efficient operation of wind turbines. In practice, there is often doubt as to what effect a specific event actually had and whether action is required. This is where robust data provides transparency. It helps assess the damage, enables transparent documentation of events and forms the basis for condition-based maintenance strategies.DEHN will be at WindEnergy Hamburg (Stand 501 in Hall B6), taking place from 22 to 25 September 2026, to demonstrate how operators can make even more targeted use of this data in future. Using real-life examples, visitors can see how lightning events are recorded, analysed and taken into account when devising appropriate operational and maintenance measures. At the trade fair, DEHN will focus on the new DEHNsphere cloud solution, which collects the recorded lightning events centrally, analyses them and provides a clear display of the relevant data. This gives operators a quick overview of recorded incidents and gives them a more in-depth understanding of their potential impact. Configurable notifications, event histories and cloud-based analytics help operators make data-driven decisions regarding inspections and maintenance and plan steps more effectively. The cloud solution also lays the foundations for integrating additional digital applications and areas of use. In future, going beyond lightning monitoring, this will unlock opportunities to centralise and evaluate data, harnessing it to ensure safe and cost-effective operation of technical systems.DEHNdetect provides the necessary data. The lightning current measurement system, developed specifically for wind turbines, records lightning events on the turbine itself and provides the relevant measurement data for analysis in DEHNsphere. The system is DNV-certified and meets the requirements of IEC 61400-24 regarding lightning monitoring for wind turbines. DEHN will also be showcasing its engineering services at the trade fair, which help operators to assess incidents and develop appropriate measures, as well as innovative ways to inspect installations using drones.

Start of Production in Piteşti – DEHN Expands Capacity for the European Market
The world is going electric. The expansion of renewable energy, the rapidly increasing number of data centers worldwide, and the growing connectivity of buildings make the electrical industry more crucial than ever. Alongside Asia and the USA, the European market is vital for DEHN. In spring 2023, the Neumarkt-based family-run company commissioned a new production facility at its Mühlhausen site. To enable greater prioritisation there and, at the same time, respond more flexibly to customer enquiries from across Europe, the company also set out to seek an additional foothold in Europe. In July 2026, productive operations commenced at the new multi-functional site in Piteşti, Romania, north-west of Bucharest. The plant focuses on the manufacture of surge protective devices, which require a high degree of manual assembly work.The newly built plant in Piteşti is the perfect addition to the existing plants in Neumarkt and Mühlhausen. Whereas high production volumes and highly automated processes dominate at those sites, the Romanian site primarily manufactures small batches of products requiringa high level of manual assembly. Just under a year after the official ground-breaking ceremony, the first surge protective devices have now rolled off the production line. Multi-functional siteFollowing an extensive search for a suitable location across Europe, Romania ultimately ticked most of the key boxes for DEHN. This south-eastern European country offers ideal location characteristics, such as good infrastructure and a ready supply of well-trained skilled workers. In future, up to 150 employees will work at the site. In addition to production and logistics, staff in HR, marketing, IT and other “shared services” will round off the multifunctional site.Strengthening the global manufacturing networkPiteşti joins the company’s global manufacturing network. Only last year, the specialist in lightning protection, surge protection and safety equipment opened a production facility in Mooresville, North Carolina, to better serve the American market from there. The new European operating location represents a key component of the company’s international strategy and enables it to respond flexibly to rising demand from European countries.

The Smarter E Europe 2026: DEHN presents protection concepts for tomorrow’s DC world
Geopolitical tensions, growing demands for energy security, and the accelerated global expansion of renewable energy are reshaping the energy sector as never before. The transition to a resilient, decentralised and largely electrified power supply is inevitable. From June 23 to 25, at The smarter E Europe 2026 in Munich, DEHN will be demonstrating how to safely navigate this development with a 360° approach to comprehensive lightning and surge protection solutions for applications increasingly characterised by direct current.The energy transition is leading to a profound restructuring of the generation, storage, and use of electrical energy. Photovoltaic systems, battery storage systems, charging infrastructure for electric mobility and smart grids are becoming increasingly important. These applications share a common technological trend with direct current (DC) increasingly taking centre stage. Due to higher efficiency, lower conversion losses, and direct integration with renewable energy sources, DC technology is considered key to the success of the energy transition.However, the increased use of DC systems is also leading to stricter electrical safety requirements. Power surges caused by lightning strikes, switching operations, or grid disturbances can damage equipment, cause outages, or, in extreme cases, lead to fires. In addition, direct current has the special characteristic that arcs are more difficult to quench than in alternating current systems. Protection concepts should therefore be designed to accommodate these conditions from the outset.DEHN meets these requirements with its patented ACI (Advanced Circuit Interruption) technology, capable of interrupting DC arc faults using an integrated switch/spark gap combination. As a member of the Open Direct Current Alliance (ODCA), the company is positioning itself at The smarter E Europe as a technology partner for safe DC infrastructures. The focus of the trade fair participation is on protection solutions for PV applications in both residential and industrial settings, as well as for free field systems, battery storage systems and smart power grids. A technological highlight in the field of e-mobility infrastructure is the DEHNguard M DC ACI 1250 FM, a modular Type 2 surge arrester designed specifically for high-power charging (HPC) and fast-charging infrastructure up to 1250 V.At DEHN’s 360° world in Hall A3, booth 120, alongside new products and customised protection solutions, the focus is on personal interaction, consultation, and dialogue on technical challenges, regulatory frameworks, and the issue of how to implement the energy transition safely and sustainably.For more information, please visit the landing page for our trade fair participation.

Smart Protection Concepts for Resilient Grid Infrastructures: DEHN at E-world 2026
The energy transition can only succeed if security of supply is consistently taken into account. The more electrification, digitalization, and renewable energy generation are expanded, the more vulnerable systems become to disruptions. At E-world energy & water 2026 in Essen, DEHN will demonstrate how critical energy infrastructures can be reliably protected against lightning and surge damage. From February 10 to 12, 2026, the company will present comprehensive protection concepts for smart energy grids, battery energy storage systems (BESS), and charging infrastructure for electric trucks and buses in Hall 6, Booth 6B140. Decentralized feeders, digital local network stations, and modern communication and control systems make power grids more efficient, but at the same time more vulnerable to disruptions. Lightning interference, surges, and EMC influences are among the key challenges. At the trade fair, DEHN will demonstrate how these risks can be specifically minimized—from risk analysis and planning to the complete implementation of protection concepts. Lightning and surge protection is a key system factor for grid stability and, consequently, for the success of the energy transition.Battery storage systems and digital local network stations, in particular, are emerging as critical components of the energy landscape. Outages have a direct impact on logistics, public transportation, industrial processes, and energy supply. DEHN presents practical protection solutions for these applications that balance both safety and cost-effectiveness. This is because companies, too, are under increasing pressure to operate in a more sustainable and efficient manner. Reasons for this include rising energy costs and new, more comprehensive political mandates for energy efficiency and climate neutrality. In Essen, DEHN experts will provide information on current regulatory requirements and share practical know-how for the efficient implementation of protection measures. They will advise on products and system solutions related to surge protection, grounding, equipotential bonding, and the protection of power and data lines, particularly in the fields of energy and e-mobility. In addition, they will present engineering services that support plant operators throughout all project phases—from risk analysis and planning to technical implementation.

DEHNventil ACI closes the gap: Advanced Circuit Interruption now extended to the area of Type 1 arresters
Digitalisation, networked systems and automation are rendering modern electrical installations increasingly complex. The rising proportion of renewable energy sources in the grid is changing its parameters in terms of short-circuit behaviour and protection technology, creating fresh challenges for planners and installers. With the new DEHNventil ACI M TNS 264 FM, DEHN is the first supplier to launch an arrester for Type 1 applications based on its ACI (Advanced Circuit Interruption) technology. The specialist for lightning and surge protection and safety equipment is thus expanding its established ACI portfolio for Type 2 arresters to create a comprehensive product family which fulfils the increasingly stringent requirements on surge protection in the field of electrical installation and planning. Conventional overcurrent protection such as fuses or circuit breakers is only to a limited extent suitable for protecting surge protective devices (SPDs), as required by IEC 60364-5-53:2001/A2:2015, as they can trigger unintentionally when exposed to lightning or impulse currents. The maximum backup fuse specified for the SPD does not reliably protect against residual currents in the range of several tens or hundreds of amperes, which can lead to thermal overload. By introducing the innovative ACI technology here, DEHN is pursuing a completely new approach. The classic overcurrent protection concept is replaced by integrating a powerful switch/spark gap combination directly into the surge protective device. In addition to offering overcurrent protection, this provides galvanic isolation in normal conditions. So, there are no leakage currents and the resistance to mains frequency temporary overvoltage (TOV) is significantly increased. This technology offers numerous advantages for planners and installers, reducing the planning effort without compromising operational safety. Dimensioning errors, questions about selectivity and complex calculations are now a thing of the past. Reliable protection on the feed-in sideBesides setting standards in the Type 2 and DC areas, ACI technology is also of central importance for protection on the feed-in side, especially for Type 1 lightning current arresters. This is where high short-circuit currents and complex network conditions come together. IEC 60364-5-53:2001/A2:2015 requires that surge protection be installed as close as possible to the feeding point of the system. In practice, this is often difficult because connection cables may not be longer than 0.5 metres in order to prevent inductive voltage drops.The modular combined arrester (Type 1+2+3) DEHNventil ACI M TNS 264 FM facilitates implementation: The integrated ACI technology eliminates the need for arrester backup fuses. The device can be mounted directly on earthed DIN rails or earthing rails. A cross-sectional area of 16 mm² Cu is always sufficient, since, even in the event of a fault, the integral current is so low that the connection cable is not thermally overloaded.The disconnection function allows the module to be replaced safely during operation, either from the side or from the front, using insulated tools.Technical details can be found here.
