The new DEHNcombo YPV combined arrester from the lightning and surge protection specialist DEHN safely protects PV systems from surges caused by lightning interference. The arrester offers a number of application advantages for PV systems in a single device. The varistor-based protective device combines a type 1 lightning current arrester and a type 2 surge arrester and incorporates a tried and tested Y circuit.
DEHNcombo YPV efficiently protects the DC side of the inverter, the combiner box or the PV modules. This new arrester can be used for small rooftop systems, but also for systems of the multi-megawatt class.
The sustainable use of resources requires the intelligent and sustainable generation, distribution and use of energy. This includes protection of the associated systems and plants. At “The Smarter E Europe“ (hall B3, booth 372) - the most important industry platform which takes place from May 15 to May 17 in Munich - we will demonstrate how to protect systems against lightning-related surges and safely handle electrical energy. The event brings together four exhibitions under one roof: Intersolar, Power2Drive, ees and EM-Power, making it the largest energy trade fair in Europe. Under the motto “DEHN protects.“, DEHN will present innovative protection solutions for photovoltaic systems, smart grids, battery storage systems and e-mobility, irrespective of the plant size. Based on practical protection solutions, the DEHN experts will explain how lightning and surge protection can increase the availability of photovoltaic systems, including the grid infrastructure and battery storage systems, or the e-mobility charging infrastructure.
The wireless inspection camera by DEHN is now available with an optional LED lighting unit which is quite simply mounted to the camera enclosure. The practical camera is ideal for inspecting and documenting the state of electrical installations up to 123 kV / 15-60 Hz – under live conditions. The extra lighting, point or diffused, makes it possible to use the camera in badly lit locations. It is simple to control via WiFi and an app on a smartphone or tablet computer. Safe operation is a simple matter, without any special training on the part of the electrician. The photos and documentation transmitted live can be saved and forwarded.
Neumarkt – Mid-December 2018: DEHN greeted over 30 lightning protection installers from all over Germany. “DEHN is already in its fourth generation and still fascinated by the phenomenon lightning, our passion. Like previous generations, we look for opportunities to meet future challenges and make the world a little bit safer through our own protection solutions and the skill of the lightning protection installers. It is our common experience in trade and industry which flows into the further development of lightning protection” said Dr Philipp Dehn in his speech on the topic: 15 years of HVI. DEHN brought its guests up to date on the development and testing of the HVI high voltage resistant insulated conductor and technical innovations and trends in the field of lightning protection. A visit to the high voltage laboratory at the Technische Hochschule Nürnberg Georg Simon Ohm rounded off the technical framework programme.
UL has intensified cooperation and qualified the DEHN Test Centre as a "Third Party Test Lab". DEHN is now authorised to carry out tests for third parties on behalf of and for UL. This once again underlines the excellent quality of the laboratory facilities and the expertise of the staff at DEHN.
The EXFS Coaxial Connection Box by DEHN is the ideal solution for integrating
electrically conductive parts in ex areas like, for instance, the insulating joints of
pipelines, in the lightning equipotential bonding.
This effectively protects those electrically conductive parts in ex areas which
cannot be directly interconnected against lightning induced surges.
The benefits for the user, above all, during installation, maintenance and testing
are significant. The Coaxial Connection Box is installed above the ground so that
the regular inspection of the integrated EXFS 100 can be conducted outside the
ex area. There is also no need to disconnect cables or remove insulation when
testing. What is more, mounting is simple because DEHN includes all fixtures and
assembly accessories in the scope of delivery.
Safe dimensioning makes the new DEHNguard with ACI technology (Advanced Circuit Interruption)a no-worries package for the user who saves space, time and costs. ACI technology presents a technical solution to dimensioning issues which eliminates the need to select the right back-up fuse or conductor cross-section. ACI fulfils the requirements of tomorrow today. Constant availability of electrical systems is a must. Power cuts and system failure are out of the question. Now and in the future, it is important to consider the ongoing transition in the global power supply. Renewable power generation is creating new grid parameters: Isolated grids and storage systems are changing the short-circuiting conditions. One aspect which the new ACI technology already has well under control.
Be it with lightning and surge protection for electronic and digital interlockings, for level crossings or point heaters - “DEHN protects the railway infrastructure”. With this motto, DEHN will be at InnoTrans, the leading international fair for transport technology, in Berlin from 18th to 21st September, 2018. At stand 218 in hall 11.1, DEHN will feature practical lightning and surge protection solutions with which to prevent costly downtime and operational disruptions. The experts at DEHN will provide information on individual solutions, the seminars available at the DEHNacademy and the testing services offered in the laboratories.
DEHN Neumarkt, Germany – Alongside the Managing Directors Dr. Philipp Dehn (CEO), Helmut Pusch (CSO) and Christian Köstler (COO), Dr. Thomas J. Schöpf can now be found as the new CTO at the helm of DEHN, a worldwide leading company for lightning and surge protection. Dr. Thomas Schöpf succeeds Dr. Peter Zahlmann, who retires after 26 years of service with DEHN.
From 20 – 22 June you will find DEHN at the leading platform for the solar industry - the Intersolar in Munich, hall A2, stand 536. Whether kilowatt or megawatt systems, DEHN protects your investments across the globe against interruptions caused by lightning currents and surges. Practical solutions show how lightning and surge protection can increase the availability of photovoltaic systems in conjunction with the network infrastructure, battery storage or electromobility.
The new surge protective device DEHNgate FF5 TV is suitable for universal application in analogue and digital SAT systems. One arrester can protect analogue or digital satellite reception systems with, e.g., a quad LNB (multi-switch) plus a terrestrial antenna.
Personal protection takes top priority when using high pressure water jets for cleaning purposes. The right protective clothing minimises the risk of accident and injury. Beside occupational safety considerations, personal protective equipment (PPE) should be comfortable to wear and provide sufficient freedom of movement. The new DEHNcare WJP overall fulfils both requirements – safety at work and comfort. The high-pressure water jet protective overall has been tested in accordance with recognised test principles (test pressure 1,200 bar) to reliably withstand water jets of up to 1,000 bar. Moreover, the innovative lightweight material does not restrict movement and is therefore comfortable to wear.
DEHNpatch outdoor is the new complete unit comprising surge protection and an enclosure for outdoor use. With IP 66 degree of protection, a universal mounting bracket (horizontal/vertical, pole or wall) and transmission class E, the new surge arrester DEHNpatch outdoor is the perfect protective device for Ethernet applications (also PoE++) in outdoor areas.
DEHN continues to focus on the internationalisation of sales activities. DEHN has been active in the Netherlands for decades. In January, it opened its own company DEHN NEDERLAND B.V. in Amersfoort. The aim is to intensify marketing activities and support customers when marketing on a local level.
Due to digitalisation, networked technology is becoming more important, equipment and components more sensitive and demands in the workplace higher. Failure of sensitive, networked technology is unthinkable and often has dire consequences.
“Connected – Secure – Convenient”, the motto of this year’s Light + Building, has also been taken up by DEHN whose stand D90 in hall 8.0 at the international trade fair for light and building technology in Frankfurt/Main from 18 – 23.03.2018 will show how to cope safely and simply with any challenges to be met in the thrilling times in which we live.
At the end of 2017, the DEHN Test Centre was awarded an accreditation certificate (Registration number D-PL-20356-01-00) by the Deutsche Akkreditierungsstelle, DAkkS (German accreditation body). For DEHN this is further objective proof of the quality and competency of its testing.
DEHN not only develops protective devices for the regenerative power generation sector, but actively promotes the use of sustainable power at its locations in Neumarkt and Mühlhausen. Solar energy and a combined heat and power plant are already used to generate electricity and provide warm water. In January, a new photovoltaic system was put into operation at the premises in Mühlhausen, producing approx. 750,000 kWh of additional electricity annually. This leads to a CO2 saving of some 350,000 kg per year. In this way, DEHN makes an important contribution towards protecting the environment and resources.
