Abstract:
This thesis analyses the lightning protection concept. After a brief introduction to lightning, lightning discharge process and the consequences of a lightning stroke, the worldwide standards for the protection of structures against lightning are analysed and compared in the scope of requirement for the lightning protection. The lightning protection systems since Franklin are traced and the protection methods are re-arranged in the basis of rolling sphere method. after discussing the changing philosophy in lightning protection, cage method is examined and applications of cage method are done

Abstract:
Wind turbines are the largest contributor to renewable energy both in Britain and the rest of Europe. With a rise in the installed capacity and an increase in offshore wind energy due to governments green targets by 2020, there has been a large development in new wind turbines for optimized performance. The present thesis deals with the uncertainties in regards to the lightning phenomenon on wind turbines with emphasis on the rotor blades. Rotor blades are the most expensive part to replace in the event of lightning related damage. The research presents results based on lightning data analysis

Abstract:
Lightning is a powerful and potentially destructive force of nature; failure to include appropriate measures in the design and construction of buildings can have severe consequences. The electrical and physical forces released during a lightning strike can result in serious damage to structures, electrical infrastructure and the sensitive electronic components used in computers, media devices and electronic systems that have become crucial to the modern existence. Developments in electronics technology have resulted in the increased proliferation of PV systems and devices that incorporate

Hydropower plants contains a lot of vital electrical power technology such as generators and transformers. To prevent damage to this equipment due to overvoltage, they are often protected by surge arrester and in some cases also by surge capacitors.

Lightning causes important transient disturbances on transmission and distribution systems, with consequent damages to equipment, outages, and general decrease of the power quality. The assessment of the lightning dielectric strength of power equipment is generally based on tests performed using the standard lightning impulse voltage (1.2 / 50 µs waveshape), although the characteristics of the lightning overvoltages depend on many parameters and may vary widely. The behavior of insulators when subject to non-standard impulses depends both on the voltage amplitude and waveshape, and therefore a

In the transmission and distribution systems, lightning transients can be caused by either direct or indirect strikes. Indirect strikes are much more frequent than direct strikes and can cause flashovers, especially when the line insulation level is low. The computatio

Therefore in creating an external LPS, it is possible to create a path for the discharge that minimizes its harmful effects to a structure. There are many international documents and standards that describe methods of providing lightning protection.

Lightning would even damage some power equipments and influence the quality of power supply. Choosing the lightning arresters which meet necessary requirements and installing them in proper locations could make the most out of the protection.The main purpose of this thesis is to discuss applying lightning arresters to lightning surge overvoltage protection for distribution power systems.

Abstract:
In concrete reinforced buildings, the steel framework is required to be bonded and is often used as a cost effective method of lightning protection. In defining lightning protection zones, it is essential to understand where the lightning current due to a direct strike will flow. A number of models exist to evaluate the current distribution, but are often applied to relatively simple structures. Using Maxwell’s equations, an approximate skin effect model is proposed and used to eval- uate the lightning current distribution in a complex structure. A reduced scale model of a structure, co

The lightning surge is then drawn into the ground grid, so the lightning protection performance of overhead ground wires is very important to the safe and reliable operation of the power system. The lightning protection performance of substations is affected by the transient characteristics of grounding grids if the direct lightning happens. And the transient characteristics of grounding grids depend up

A lightning stroke produces high voltage and large current that will cause the damage of everything which is attacked by the lightning stroke directly. Besides, lightning stroke can damage the people, animals, and objects around indirectly. Then the overhead transmission lines erected in open fields are much easier to be attacked by thunderbolt.
