The insulating material used in low-voltage (LV) distribution cables is predominantly PVC. Furthermore, the presence of cables with different structures in the grid poses challenges in detecting the aging of the cable network. Finding a universal and dependable condition-monitoring technique that can be applied to various types of cables is indeed a challenge. The diverse construction and materials used in different cables make it difficult to identify a single monitoring approach that can effectively assess the condition of all cables. To address this issue, this study aims to compare the thermal aging behavior of different LV distribution cables with various structures, i.e., one cable contains a PVC belting layer, while the other contains filler material. The growing adoption of distributed generation sources, electric vehicles, and new consumer appliances in low-voltage distribution grids can lead to short, repetitive overloads on the low-voltage cable network. Hence, these cable samples were exposed to short-term cyclic accelerated aging in the climate chamber at 110 °C. The cable’s overall behavior under thermal stress was evaluated through frequency and time domain electrical measurements (including tan δ and extended voltage response) and a mechanical measurement (Shore D). The tan δ was measured in the frequency range of 20 Hz–500 kHz by using the Wayne-Kerr impedance analyzer. The extended voltage response measurement was conducted using a C# application developed in-house specifically for laboratory measurements in the .NET environment. The study observed a strong correlation between the different measurement methods used, indicating that electrical methods have the potential to be adopted as a non-destructive condition-monitoring technique.}, year = {2024}, eissn = {2079-9292}, orcid-numbers = {Tamus, Zoltán Ádám/0000-0002-0092-7565} } @inproceedings{MTMT:34470803, title = {A koronavírus megbetegedési és halálozási adatainak Fourier-analízise}, url = {https://m2.mtmt.hu/api/publication/34470803}, author = {Drajkó, Szonja Imola and Tamus, Zoltán Ádám}, booktitle = {Orvosi informatika.

This work investigates the change in the dielectric properties of low-voltage cable insulation caused by short-term overloads, examining how the cable structure affects the dielectric characteristics of the cable specimens in the case of cyclic short-term thermal aging. PVC-insulated low-voltage cable samples were exposed to an accelerated aging test in a temperature-controlled oven after changing their structures by removing different layers. Three aging cycles, each of six hours, were applied to the samples. After each cycle, the tan δ and capacitance were measured by an Omicron DIRANA Dielectric Response Analyzer in the laboratory at room temperature 24 ± 0.5 °C. Furthermore, the polarization and depolarization currents were also studied. The results show that changing the cable structure impacts the dielectric parameters; in particular, the effect of the belting layer is significant. From the point of view of aging, the PVC belting layer protects the diffusion of the plasticizers of the inner structure. The findings of the study show that an asymmetric aging phenomenon can be observed in different polymeric components of the cables, even though the cables were aged in an air-circulated oven ensuring a homogeneous temperature distribution in the samples.}, year = {2023}, eissn = {2073-8994}, pages = {1186}, orcid-numbers = {BAL, Semih/0009-0001-6238-0745; Tamus, Zoltán Ádám/0000-0002-0092-7565} } @inproceedings{MTMT:33733404, title = {Analyzing the Effect of Thermal Stress on Dielectric Parameters of PVC Insulated Low Voltage Cable Sample}, url = {https://m2.mtmt.hu/api/publication/33733404}, author = {BAL, Semih and Tamus, Zoltán Ádám}, booktitle = {IEEE 5th International Conference and Workshop in Óbuda on Electrical and Power Engineering (CANDO-EPE 2022)}, doi = {10.1109/CANDO-EPE57516.2022.10046360}, unique-id = {33733404}, year = {2022}, pages = {000067-000072}, orcid-numbers = {Tamus, Zoltán Ádám/0000-0002-0092-7565} }
