With the spread of photovoltaic power plants, new challenges are emerging for experts to maintain grid stability due to their dependence of sunlight intensity. The fact, that power generation of these power plants can be unpredictable, must be considered. In addition, growing in numbers also means that the lightning protection of photovoltaic power plants is more and more important to ensure their energy generation during appropriate weather conditions. According to the standardized procedure, the lightning protection of these systems can be constructed. The paper indicates, the calculations strictly based on the standard are leading to a protection system that is not cost-efficient and – in most cases – elements of the primary protection system can be neglected without significantly lowering the protection level. In order to demonstrate a more efficient way to create primary protection, a real photovoltaic power plant is featured in this article. The method to examine the geometry and plan a more efficient primary lightning protection system is based on the PMAS theory. Different zones of the examined photovoltaic power plant are selected to present the calculation.}, keywords = {Lightning protection; PMAS; photovoltaic power plants; lightning protection zone concept}, year = {2021}, pages = {01-6}, orcid-numbers = {Kálecz, György/0000-0002-0921-6946; Tóth, Zoltán/0000-0002-0429-0629} } @article{MTMT:31882887, title = {Beszámoló a Villámvédelmi Munkabizottság 2020. 10. 08-i üléséről}, url = {https://m2.mtmt.hu/api/publication/31882887}, author = {Szedenik, Norbert and Varga, Tamás and Tóth, Zoltán}, journal-iso = {ELEKTROTECHNIKA}, journal = {ELEKTROTECHNIKA}, volume = {2021}, unique-id = {31882887}, issn = {0367-0708}, year = {2021}, pages = {26-26}, orcid-numbers = {Tóth, Zoltán/0000-0002-0429-0629} } @article{MTMT:32904859, title = {Editorial: Actual Questions in Power Engineering}, url = {https://m2.mtmt.hu/api/publication/32904859}, author = {Szedenik, Norbert}, doi = {10.3311/PPee.14845}, journal-iso = {PERIOD POLYTECH ELECTR ENG COMP SCI}, journal = {PERIODICA POLYTECHNICA-ELECTRICAL ENGINEERING AND COMPUTER SCIENCE}, volume = {63}, unique-id = {32904859}, issn = {2064-5260}, year = {2019}, eissn = {2064-5279}, pages = {133} } @inproceedings{MTMT:31126221, title = {Relation Between The Material of Roof and The Risk of Lightning Caused Damage}, url = {https://m2.mtmt.hu/api/publication/31126221}, author = {Tóth, Zoltán and Kiss, István and Németh, Bálint and Szedenik, Norbert}, booktitle = {2019 International Symposium on Lightning Protection (XV SIPDA)}, doi = {10.1109/SIPDA47030.2019.8951630}, unique-id = {31126221}, year = {2019}, pages = {1-4}, orcid-numbers = {Tóth, Zoltán/0000-0002-0429-0629} } @article{MTMT:30750449, title = {Biztonságos nyaralás villámok között}, url = {https://m2.mtmt.hu/api/publication/30750449}, author = {Tóth, Zoltán and Szedenik, Norbert}, journal-iso = {ELEKTROTECHNIKA}, journal = {ELEKTROTECHNIKA}, volume = {112}, unique-id = {30750449}, issn = {0367-0708}, year = {2019}, pages = {5-7}, orcid-numbers = {Tóth, Zoltán/0000-0002-0429-0629} } @inproceedings{MTMT:30974890, title = {Developed Simplification of the Risk Assessment}, url = {https://m2.mtmt.hu/api/publication/30974890}, author = {Szedenik, Norbert and T, Bodócs and Kiss, István and Berta, István}, booktitle = {Proceedings of the "33rd International Conference on Lightning Protection - ICLP 2016”}, unique-id = {30974890}, year = {2016} } @inproceedings{MTMT:3003362, title = {Simplified risk assessment of lightning protection}, url = {https://m2.mtmt.hu/api/publication/3003362}, author = {Szedenik, Norbert and Bodocs, T and Berta, István}, booktitle = {2014 International Conference on Lightning Protection (ICLP)}, doi = {10.1109/ICLP.2014.6973262}, unique-id = {3003362}, abstract = {The risk assessment in IEC 62305 international lightning protection standard is very detailed, it requires deep analysis for every possible condition. After 8 years the standard was published, the feedbacks of the engineers show that the collection of all the data requires much time. Furthermore, in most cases these data are not available. For this reason, the engineers need to estimate the missing parameters, generally in a conservative way. Of course, the effect of these adjustments appears in the results of the risk assessment as well, which results more severe measures, as it would be necessary. To handle the problems mentioned above, we have elaborated a simplified risk assessment process.}, keywords = {STANDARDIZATION; risk assessment; Simplification; risk of fire; lightning density; height of structure}, year = {2014}, pages = {961-965} } @article{MTMT:2692992, title = {Sensitivity analysis in lightning protection risk management}, url = {https://m2.mtmt.hu/api/publication/2692992}, author = {Farkas, T D and Szedenik, Norbert and Kiss, István}, doi = {10.1016/j.elstat.2012.12.040}, journal-iso = {J ELECTROSTAT}, journal = {JOURNAL OF ELECTROSTATICS}, volume = {71}, unique-id = {2692992}, issn = {0304-3886}, abstract = {The total risk R can be expressed by the following equation: R = NPL, where N is the number of dangerous events, P is the probability of damage and L measures the amount of loss. These parameters can be regarded as macroparameters in the sense that they can be given as a function of additional parameters (microparameters).Methods of calculation, check and refinement of parameter values have always been general themes of the standardization. The comparison of standards IEC 62305-2:2006 Ed. 1 and IEC 62305-2:2010 Ed. 2 is a good example of these efforts, as changes underwent in the determination of the collection area of service and the value of some parameters, moreover new parameters were introduced in order to break existent parameters into more components.Though the international standard contains the value of parameters, it does not give any information about the procedure how these values were determined, nor about the theoretical considerations behind. Therefore it is proper to ask whether the changes of a given parameter value or introduction of a new parameter make radical changes in resulting risk value or not.In this study sensitivity analysis was used to investigate how the individual macro- and micro parameters influence the risk. Moreover it was determined whether or not new parameters and calculations have an effect on the importance of the respective components of the resulting risk.The sensitivity analysis was done for two case studies in the standard, a country house and an office building respectively, with both editions of the standard. © 2013 Elsevier B.V.}, keywords = {RISK; STANDARDIZATION; Sensitivity analysis; Lightning protection}, year = {2013}, eissn = {1873-5738}, pages = {582-585} } @article{MTMT:2692657, title = {Investigation of temperature dependence of dielectric processes in thermally aged PVC insulation}, url = {https://m2.mtmt.hu/api/publication/2692657}, author = {Tamus, Zoltán Ádám and Szedenik, Norbert}, doi = {10.1016/j.elstat.2013.01.003}, journal-iso = {J ELECTROSTAT}, journal = {JOURNAL OF ELECTROSTATICS}, volume = {71}, unique-id = {2692657}, issn = {0304-3886}, keywords = {CONDUCTIVITY; Polarisation conductivity; Dielectric processes; Voltage response; Insulation resistance; Polyvynil chloride}, year = {2013}, eissn = {1873-5738}, pages = {462-466}, orcid-numbers = {Tamus, Zoltán Ádám/0000-0002-0092-7565} }
