Lightning - Induced Voltages on Overhead Distribution Lines : Theoretical and Experimental Investigation of related Problems and their Impact on Power Quality
Recent power quality studies have been focused on the source-identification of voltage disturbances at distribution network busses. This paper describes a method aimed at correlating indirect-lightning events with power systems relay operations, associated with voltage dips. The proposed method, based on the coordinated use of the Italian lightning location system CESI-SIRF, the Italian monitor...
متن کاملCalculation of Lightning-induced Voltages in MODELS Including Lossy Ground Effects
The paper outlines how lightning-induced voltages (LIV) in multi-conductor overhead lines can be calculated in MODELS in the ATP-EMTP. Lossy ground effects on the radial electrical field is taken into account by the CoorayRubinstein approximation, but the overhead line itself is assumed to be lossless. This is a reasonable assumption for line lengths up to 1-3 km, depending on the ground resist...
متن کاملGeneration of Transient Voltages Due to Direct Lightning on Grounding Grids
The analysis of EMC problems caused by transient current and voltage on grounding grids created by lightning surges is carried out in the present work. Although this problem is considered by Zago.F et al. [26] complete data on the variation of transient voltages as a function of time under different resistivity conditions is not available. Considering the TLM concept has reported by Zago.F comp...
متن کاملTheory and Observations of Controls on Lightning Flash Size Spectra
Previous analyses of very high frequency (VHF) LightningMappingArray (LMA) observations relative to the location of deep convective updrafts have noted a systematic pattern in flash characteristics. In and near strong updrafts, flashes tend to be smaller and more frequent, while flashes far from strong vertical drafts exhibit the opposite tendency. This study quantitatively tests these past ane...
متن کاملLightning induced atrial fibrillation.
Atrial fibrillation (AF) is a common arrhythmia that occurs in paroxysmal and persistent forms. It occurs in varied situations but lightning induced AF is extremely rare. Here is a case which reverted to sinus rhythm spontaneously. This 37-year-old man without any underlying heart disease had new onset AF after being struck by a lightning. Oral Metoprolol alone was given to control ventricular ...
