Research and Application of Active Lightning Protection Technology
نویسنده
چکیده
The conventional passive lightning protection mode depending on fixed lightning rods, overhead grounded wires, arresters and SPDs couldn’t fit for the demand in practice gradually. Therefore, it is necessary to explore an available and optional way that could enhance and improve them. Based on Intelligent Control Technology and combined with lightning detection, the Active Lightning Protection (ALP) was researched. Active Lightning Protection means carrying out preventive measures in advance according to the real time lightning tracing information. It combined protection with lightning detection, and is different from the passive lightning protection mode. The ACTIVE mode more emphasizes the dynamic measures before potential hazards but not just waiting to be stroke. Accordingly, the ALP could be applied to many important industries and critical fields.

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.
