Lightning and surge protection standards technical training course
Latest updates on BS EN IEC 62305 Edition 3
We can run additional and in-company courses dependent on demand. Please contact us if you're interested.
About the technical training course
This course is your essential guide to the latest lightning and surge protection standards.
This exclusive two-day course is led by Alain Rousseau, a globally recognised authority with 40 years of experience and leadership roles as:
- Chair of IEC Lightning Protection Technical Committee
- Vice Chair of the IEC Surge Protective Device Committee
- Chair of CENELEC Lightning Protection Technical Committee
- Chair of the Scientific and Technical Committee of the French Lightning Protection Association
- Convener of the IEC SPD application working group, Lightning Risk Analysis working group and the Thunderstorm Warning System working group.
Alain will guide you through all the recent updates to BS EN IEC 62305, ensuring you understand the new requirements and best practices.
Key learning objectives
Day one
On day one, an update on the new standards and their implications: IEC 62305-1, -3 and -4 on Lightning Protection Systems and IEC 61643 series of standards for Surge Protective Devices.
Note: 62305-2 is presented on day two due to major changes introduced by edition 3.
Day two
The IEC 62305-2, third edition, lightning risk analysis standard has introduced many changes.
The details of the methodology and its new features will become clear at the end of the day.
Who should attend?
Engineers, managers, technicians, electricians, consultants, designers, inspectors who are responsible for electrical safety or work in high-risk facilities.
Organisations who need to adhere to:
- COMAH – control of major accident hazards
- DSEAR – Dangerous substances and explosive atmospheres regulations.

More than 40 years experience in lightning and surge protection and in standards development. He has experience as a user (at EDF), as a contractor (Vinci), as a manufacturer (Soulé and Erico), as a study and engineering company (SEFTIM) from 2000 to May 2026 and since then as a consultant (ARC).
He operates worldwide for lightning and EMC protection of sensitive installations - wind power, photovoltaics, ocean energy, radars, explosives, petrochemicals, nuclear, rail transport, national heritage sites, public-access buildings, leisure parks, golf courses, resorts.
He has written more than 150 international publications and is the editor of a book on Surge Protective Devices.
His main topic of interest are people protection against lightning, thunderstorm warning systems, risk assessment and application of SPDs.
- Day one

08.40 Teams open 08.45 Welcome 09.00 IEC 62305-1: This part of IEC 62305 provides general principles for the protection of structures against lightning, including their installations and contents, as well as persons:
- Introduction
- Lightning current parameters (distribution)
- Damage due to lightning (effect of lightning current)
- Need for lightning protection (introduction to lightning risk analysis)
- Protection measures (Lightning Protection System and Surge Protection Measures)
- Basic criteria for protection of structures (Lightning protection levels and Lightning protection zones)
10.30 Break 10.45 IEC 62305-3: This part of IEC 62305 provides the requirements for protection of a structure against fire, explosion or physical damage by means of a lightning protection system (LPS), and for protection against injury to human beings due to touch and step voltages in the vicinity of an LPS or on its roof and terraces:
- Lightning protection system (LPS)
- External lightning protection system (attached or not to the structure)
- Isolated LPS or an electrically insulated LPS
- Air-termination system
- Air termination system against side flashes
- Natural components (metal thickness)
- Down-conductors
- Earth-termination system (local or earth loop)
12.00 Lunch 13.00 IEC 62305-3 Presentation (continued):
- Lightning Protection Components (IEC 62561 series)
- Internal lightning protection system (bonding and Surge Protective Devices)
- Separation distance
- Maintenance and inspection of an LPS
- Protection measures against injury to human beings due to touch and step voltages
14.00 Break 14.10 IEC 62305-4: This part of IEC 62305 provides requirements for the design, installation, inspection, maintenance, and testing of surge protection measures (SPM) for electrical and electronic systems to reduce the risk of permanent failures due to lightning electromagnetic impulse (LEMP) within a structure:
- Design and installation of SPM and Lightning protection zones (LPZs)
- Magnetic shielding and line routing
15.10 Break 15.20 IEC 62305-4 Presentation (continued):
- Coordinated SPD system
- Isolating interfaces

08.40 Teams open 08.45 Welcome 09.00 IEC 62305-2: This part of IEC 62305 is applicable to the risk management of a structure due to lightning flashes to earth. Risk management also includes the evaluation of frequency of damage of internal systems caused by surges due to lightning flashes to earth:
- Damage and loss
- Risk and risk components
- Risk assessment: basic equation
- Partitioning of a structure in risk zones ZS
- Partitioning of a line into sections SL
- Frequency of damage and its components
- Procedure to evaluate the need of protection for frequency of damage F
10.30 Break 10.45 IEC 62305-2 Annexes:
- Assessment of annual number of dangerous events N
- Assessment of probability of damage P
12.00 Lunch 13.00 IEC 62305-2 Annexes (continued):
- Assessment of loss L
- Detailed investigation of additional losses LE related to Surroundings
- PSPD evaluation
15.00 Break 15.15 Examples:
- Private house
- Office building
- Hospital
- Data center
