a unique high frequency transient overvoltage surge suppressor for the protection of motors and transformers from steep wave-front, short rise-time, high magnitude, spikes, surges and other transient voltages, generated by switching, lightning and other sources. The protective characteristics of ZORC: Eliminates inter-turn insulation failures Extends the life of machine insulation Eliminates mu...

In this study, the lightning protection system and grounding of one plant petrochemical industry were investigated, evaluated, improved. The methods used in study rolling sphere angle methods. building under was modeled simulated using ATP/EMTP (Alternative Transient Program/Electromagnetic Program) software. results show that external prilling tower studied does not adhere to IEC 62305 1024-1-...

[1] We examine the implications of new estimates of the anthropogenic and lightning nitrogen oxide (NOx) source for the budget of oxidized nitrogen (NOy) over the United States in summer using a 3‐D global chemical transport model (Model of Ozone and Related Tracers‐4). As a result of the Environmental Protection Agency (EPA) State Implementation call, power plant NOx emissions over the eastern...

This article highlights challenges in aircraft design focusing on lightning protection of an radome. A Multiphysics analysis is performed conjunction with various laboratory high voltage test configurations, and the effects temperature pressure are discussed.

After a brief review of varistor fundamentals, including a discussion of the infamous " speed of response " issue, the report describes several unconventional packaging implementations of varistor material (usually a flat disc between metallized electrodes), such as molded axial package, bulkhead connectors, coaxial mounting, reconstituted material, and varistor substrates with surface conducti...

In order to evaluate the impulse magnetic field distribution inside buildings truck by lightning or by nearby stokes, a set of measuring system composed of self-made magnetic detection coil and fiber transmission system was developed. The sensitivity coefficient of the optical fiber transmission system was calibrated by sine wave generator. Connecting the output of a portable 8/20μs current gen...

although lightning is an uncommon phenomenon in nature; it can cause many destructive incidents. in the event of a lightning strike, multiple organs particularly the cardiovascular systems are at risk of injury. short-term mortality depends on its cardiac effects. in this paper, the authors report the development of myocardial infarction and pericardial effusion after lightning injury, a typica...
