Lightning protection inspections
A lightning strike can cause devastating fires and complete failure of sensitive electronics. We inspect your air-termination systems, down conductors, and surge protection (internal lightning protection) to ensure they are fully functional and comply with VDE standards for reliable building protection.

Lightning protection testing according to VDE 0185-305: legally compliant building protection
A direct lightning strike or induced overvoltages can cause devastating damage to your building infrastructure and the entire systems technology within milliseconds. For manufacturing companies and data centers, the failure of these systems means not only catastrophic downtime, but also immense financial losses. Under the Industrial Safety Ordinance (BetrSichV) and DGUV Regulation 3, the legislator requires operators to continuously demonstrate the effective condition of their lightning protection systems. If complete documentation is missing in the event of damage, there is a risk of full loss of insurance coverage as well as personal liability for management. Bittermann Elektrotechnik GmbH eliminates this risk through expert testing and ensures the ongoing protection of your investments.
Our inspection services in detail
As certified experts, we audit your entire lightning protection systems strictly in accordance with the standards of DIN EN 62305-3 (VDE 0185-305-3). Our process includes a detailed visual inspection of air-termination systems and down conductors as well as highly precise measurement of earth resistance. In doing so, we assess not only the external building protection, but also analyze the critical interfaces to internal lightning protection (surge protection) in order to protect your sensitive power electronics from high-energy transients. All data is recorded in an audit-proof database compliant with TRBS, providing your responsible electrically qualified persons (VEFK) with completely court-admissible documentation for every audit.
