Some inconveniences regarding the use of large RC with circumference about 6 m to 20 m, namely closeness to resonance frequency during measuring, loss of low-frequency components of the current impulse tail part can be eliminated by presented here measuring circuit. Basically, this circuit represents a new approach of lightning current measuring, which was tested in laboratory and during real lightning events on a communication tower. The results are depicted and discussed in detail in this paper. Moreover, the possibility to measure both impulse and continuous current (CC - upward lightning from high measuring object) from the same RC is considered. Some time and frequency domain network simulations were carried out in EMTP-ATP and compared with transient and frequency response measurements. Our scientific investigations were simplified by using scripts, initially developed in FAMOS and in MathCAD. The algorithms and results of their work are presented here as well. Also, in order to obtain precise measurements, some measures against electromagnetic interferences have been realized.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114781890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting model is able to represent in detail many of the most important dynamic processes occurring in the transition from the leader channel to the return-stroke channel. A parametric study is performed to identify the influence of corona parameters on the resulting vertical electric fields for a lossy channel.

An electromagnetic theory approach based on the method of moments is used. This method allows for a transient analysis and accounts for the effects of soil resistivity. Calculations are performed in the frequency domain for a simplified case where the lightning channel is modeled assuming a constant current along the channel. The model is selected for ease of comparisons with the examples described in the IEC 62305-4 standard. A time domain numerical analysis is carried out to estimate the influence of soil resistivity on the radiated magnetic field. The effect of the soil resistivity on both the resultant and on the time derivative of the magnetic field is investigated for a 2 m mesh grid-like spatial shield of 10x10x10 m located in horizontally layered soil structures. Examples of transient resultant magnetic field induced by a typical positive stroke on a building represented as a grid like shield are presented, emphasizing the impact of soil resistivity. It is shown that the transient electromagnetic field is moderately affected by soil resistivity changes which, therefore, can be, in some cases, neglected in the computation process.","PeriodicalId":216871,"journal":{"name":"2013 International Symposium on Lightning Protection (XII SIPDA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134030852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
