The “DIN EN 62305 (VDE 0185-305) Lightning Protection” standard, published by the German Institute for Standardization (DIN), consists of sub-sections published under the same title. The DIN EN 62305 (VDE 0185) series of standards is a general concept for lightning protection and comprehensively considers the following:
Therefore, the DIN EN 62305-1 standard provides information on the dangers associated with lightning exposure, types of losses, the need for lightning protection, and possible protective measures. It also offers an overview of the complete series of standards for lightning protection and, based on the following sections, explains the procedure and protection principles.
The appendices include lightning current parameters and lightning protection levels, the time function of lightning current and its simulation for testing purposes, test parameters for lightning protection components, and the determination of overvoltages caused by lightning at different installation points.
DIN EN 62305-2 applies risk analysis to first determine the need for lightning protection for structures and then select the most technically and economically suitable protection measures, as detailed in existing protection standards. Finally, the remaining risk is determined. The appendices to this standard include an assessment of the number of hazardous lightning-related events, the probability of damage to structures, and losses. A cost-benefit analysis for economic losses is explained. Case studies for structures have been conducted.
DIN EN 62305-3 addresses the protection of buildings against direct lightning-induced physical damage and life-threatening situations. This consists of external lightning protection systems (air termination systems, subconductor systems, earthing termination systems) and internal lightning protection systems (lightning equipotential bonding, separation distance). The characteristics of a lightning protection system are determined by the level of protection, which is based on the relevant lightning protection level. The appendices to this standard deal with the positioning of air termination systems, the minimum cross-sectional area of cable shields to prevent dangerous spark formation, and the share of lightning current flowing in subconductor systems for evaluating separation distances. Additional information on lightning protection in buildings with a risk of explosion and guidelines for the design, construction, maintenance, and inspection of lightning protection systems are also included.
The DIN EN 62305-4 standard addresses the protection of structures with electrical and electronic systems against the effects of lightning electromagnetic pulses using surge protection measures. These include an individual combination of the following protective measures: grounding and bonding, shielding of internal lines, routing and shielding of lines, and a coordinated surge protection device. The characteristics of the protective measures must correspond to the selected lightning protection level. The basis for the construction of surge protection measures is the concept of the lightning protection zone. The appendices to this standard provide the basis for the assessment of the electromagnetic environment in a lightning protection zone. Additional information is provided on surge protection measures in existing structures and the rules for installing a coordinated surge protection system with surge protection devices.
The DIN EN 62305 standard is the German version of the European standard EN 62305, which is compliant with the “IEC 62305-1 Lightning Protection” series of standards published by the International Electrotechnical Commission (IEC). This comprehensive standard provides guidelines for protecting structures, people, and electrical/electronic systems from lightning strikes. The BU-u standard has superseded previous national standards and represents a risk-based, holistic approach to lightning protection.
The DIN EN 62305 standard consists of four main sections:
For the purposes of these standards, the following fundamental concepts apply:
This standard provides cost-effective and customized protection while minimizing risks from direct lightning strikes, induced overvoltages, and electromagnetic interference. It is widely used throughout Europe and influences global practices.
