Lightning Protection of Ehv Substations in Iran
Extra high voltage (EHV) substations are extremely vulnerable to the hazard of lightning strokes therefore, the shielding of these substations with a highly reliable protective scheme (shield wires) is an essential undertaking. In this paper an attempt is made to clarify the design procedure for shielding EHV substations against lightning with special reference to Iran.
متن کاملLightning Protection
Lightning causes deaths, injuries, damages, and significant costs and losses around the world. The global lightning flash rate is in the range of 40 to 100 lightning flashes per second, of which about 30 % are cloud-to-ground flashes. The development of theoretical and experimental researches is crucial for a better understanding of the physical phenomenon and for the characterization of lightn...
متن کاملLightning Discharge and Fundamentals of Lightning Protection
A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the topological shielding are presented. Bonding require...
متن کاملThe Lightning Protection International Standard
The Technical Committee on Lightning Protection of the International Electrotechnical Commission (IEC TC81) has finalised the new presentation of its work in four parts from general principles and risk management, to physical damage, life hazards and protection against electrical and electronic systems within structures. In this invited lecture we summarise their content and criticise the optio...
متن کاملAvionics lightning protection design GUI
In order to build aircraft that are lighter and thus, use less fuel, aircraft manufacturers have begun using carbon composite material to fabricate the airframes instead of aluminum. An undesired effect of this change is the increase in severity of the indirect effects of lightning strikes to the airframe on the electrical equipment used on the aircraft (avionics). The more severe lightning tra...
