About DEHN / elvatec
elvatec ag, based in Altendorf (Switzerland), is part of the DEHN Group, whose parent company is DEHN SE, founded in 1910 in Neumarkt. DEHN develops and manufactures products for lightning protection, surge protection, earthing, equipotential bonding and electrical safety, including surge arresters for power and information technology, insulated HVI conductor systems, air terminals, clamps, equipotential bonding bars, arc fault protection systems and personal protective equipment. In addition to its standard portfolio, the company offers custom solutions for lightning protection and earthing, such as air terminals in special lengths for higher wind loads, clamps for non-standard cross-sections or equipotential bonding bars for higher short-circuit currents. At the 800 m², DAkkS-accredited testing and test centre in Neumarkt (accredited to DIN EN ISO/IEC 17025), system components are tested with lightning currents up to 400 kA (10/350 µs); a PV simulator allows tests up to 1500 V and 150 kW. The solution groups cover buildings, energy, mobility and process technology, with references including AlpTransit Gotthard, the Helmholtz-Zentrum Berlin and Charité.

Technologies and Processes
ACI technology (Advanced Circuit Interruption)
Integrated switch-spark gap combination makes an external upstream fuse unnecessary and increases system availability.
RAC spark gap technology
Instantly limits the grid follow current, thereby increasing the service life of arresters and downstream devices.
HVI conductor technology
High-voltage-resistant, insulated conductor routing for simple compliance with separation distances in external lightning protection.
Direct Current Disconnection (DCD)
Safe interruption of DC currents in PV and DC applications without zero crossing.
actiVsense
Automatic signal level detection for universal combined arresters up to 180 V.
LifeCheck monitoring
Permanent monitoring of arrester status to detect electrical and thermal stresses.
