DGUV Regulation 3 (formerly BGV A3)
DGUV V3 is the central accident prevention regulation for electrical systems and equipment. We take care of the proper execution and legally compliant documentation for you, as well as support with deadline monitoring, so that you are always well protected during inspections by employers' liability insurance associations or insurance companies.

Legally compliant DGUV Regulation 3 inspection: liability protection & system availability
The compliant implementation of DGUV Regulation 3 (formerly BGV A3) forms the foundation for the safe and highly available operation of your entire electrical infrastructure. Whether it is a networked production plant, complex building management technology, or IT equipment – as the operator, you are under an absolute obligation under the German Ordinance on Industrial Safety and Health (BetrSichV) to prove the safety of your systems. In the event of damage without complete, standards-compliant documentation, allegations of organizational negligence are unavoidable, which can result in the loss of insurance coverage and the personal liability of management. Bittermann Elektrotechnik GmbH offers you a legally secure solution that eliminates your liability risks while also ensuring the uninterrupted productivity of your operational processes.

Our measurement and testing portfolio includes precise analysis of protective conductor and insulation resistance, as well as validation of the exact tripping parameters of your RCD protective devices. We transfer all measurement data directly on site into an audit-proof database compliant with TRBS and create court-admissible inspection reports for you, including clear recommendations for action. We also actively support your responsible electrical specialists (VEFK) in the legally compliant definition and optimization of inspection intervals based on well-founded risk assessments in accordance with § 3 BetrSichV.
