The subject provides an introduction to lightning discharge physics and deals with protections against their effects. Students are familiarized with the design, testing, and implementation of protections. Risk management methods for lightning damage are discussed. The course includes an excursion to the production of lightning current arresters and a real study of the effects of lightning currents in the laboratory supported by numerical simulations.


Active participation in lectures and seminars, group and individual work on seminar project are expected. Entry requirements envisaged mathematics, physics, electrical engineering and economics.

Syllabus of lectures:

1. Introduction - the phenomenology of lightning discharge and the formation of atmospheric surges

2. Identification of the type of lightning discharge IC and CG

3. Methods for detection of lightning discharges, and their economic context

4. Warning and monitoring systems before the thunderstorm activity and protection systems and their economic results

5. Physical, mathematical, and numerical models of the effects of lightning discharges

6. Comparison of natural lightning with artificial interventions in the clouds

7. Global and local characteristics distribution of atmospheric discharges

8. Development of protective equipment against direct and indirect intervention lightning discharges, and their application in economic terms

9. Methods of identification, disclosure, management, assessment, and evaluation of the risks of damage caused by atmospheric discharge based on IEC 62305 - insurance, predictive schemes

10. The test and certification methods of resistance to atmospheric surges

11. Election of the level of protection against lightning (LPS) - economic and technical choice

12. Methods proposal for external and internal protection against lightning discharges at the facility and amenities for electronic equipment - the economic possibilities of the use of protection

13. Protection from atmospheric discharges in specific environments - air traffic, explosive environments, places with extreme frequency interference, solar and wind power

14. Summary findings reserve

Syllabus of tutorials:

1. Introduction to lightning current laboratory.

2. Measurement on a 10/350 wave lightning current generator.

3. Measurement of an 8/20 wave lightning current generator.

4. Thermal and mechanical effects of lightning discharge.

5. High-speed recording and analysis of discharge.

6. High-speed recording and analysis of discharge.

7. Measurement on varistor, transil, and suppressor diode.

8. Selection of overvoltage protection.

9. Methods for measuring earth resistance - potential gradient method, Wenner method, and current clamp.

10. Examples of lightning effects simulations (ATP, EMA, COMSOL).

11. Examples of lightning effects simulations (ATP, EMA, COMSOL).

12. Laboratory task of lightning discharge effects with verification using numerical simulation.

13. Risk management of damage - analysis of site situation after lightning strike.

14. Risk management of damage - project for a given space.

Study Objective:

The aim of the course is to familiarize students at the Czech Technical University in Prague with the issue of lightning discharges and protections against their effects. Graduates of the course will be able to assess the impact of lightning discharge on electrical installations and design external and internal protection against their effects. Emphasis is also placed on the implementation of protections in specific environments and alternative energy sources.
