Controlling the thermal environment of underground cable lines using the pavement surface radiation properties
Klimenta, Dardan; Perović, Bojan; Klimenta, Jelena; Jevtić, Milena; Milovanović, Miloš; Krstić, Ivan (IET Generation, Transmission & Distribution, 2018-05-03)The main purpose of this study is to show how the emissivity and absorptivity of a pavement surface aboveunderground cables affect their ampacity. The use of cool pavements whose surfaces absorb less heat ... -
The effect of solar radiation on the ampacity of an underground cable with XLPE insulation
Klimenta, Dardan; Jevtić, Miroljub; Klimenta, Jelena; Perović, Bojan (The 4th Virtual International Conference on Science, Technology and Management in Energy (eNergetics 2018), 2018-10)The main purpose of this paper is to quantify the thermal effect of solar radiation on the ampacity of a low voltage underground cable with cross-linked polyethylene (XLPE) insulation. The quantification was performed for ... -
Eliminating the effect of hot spots on underground power cables using cool pavements
Klimenta, Dardan; Tasić, Dragan; Perović, Bojan; Klimenta, Jelena; Milovanović, Miloš; Anđelković, Ljiljana (Electrical Engineering, 2019-10-24)It is well known that hot spots limit the ampacities of underground power cables. There are many commonly applied methods to control the thermal environment in hot spots of underground power cables. However, applications ... -
INCREASING THE AMPACITY OF UNDERGROUND POWER CABLES BY AN APPLICATION OF PHOTOVOLTAIC PAVEMENTS
Klimenta, Dardan; Jevtić, Miroljub; Klimenta, Jelena; Perović, Bojan (2018-10)This article shows that a significant increase in the ampacity of an underground cable line can be achieved, if a photovoltaic pavement in combination with a ventilation channel is applied along the entire length of the ... -
Increasing the ampacity of underground power cables by an application of photovoltaic pavements," The 6th International Conference on Renewable Electrical Power Sources
Klimenta, Dardan; Jevtić, Miroljub; Klimenta, Jelena; Perović, Bojan (The 6th International Conference on Renewable Electrical Power Sources "6th ICREPS", 2018-10)This article shows that a significant increase in the ampacity of an underground cable line can be achieved, if a photovoltaic pavement in combination with a ventilation channel is applied along the entire length of the ... -
Modelling the thermal effect of solar radiation on the ampacity of a low voltage underground cable
Klimenta, Dardan; Perović, Bojan; Klimenta, Jelena; Jevtić, Milena; Milovanović, Miloš; Krstić, Ivan (International Journal of Thermal Sciences, 2018-08)Compared with other underground cables, low voltage cables are most intensely heated by the sun due to the low laying depth. Accordingly, the main purpose of this paper is to show how the heat of solar radiation affects ... -
A review on new methods for increasing the ampacity of underground power cables: Cool and photovoltaic pavements
Klimenta, Dardan; Jevtić, Miroljub; Klimenta, Jelena; Perović, Bojan (The 6th International Conference on Renewable Electrical Power Sources (6th ICREPS), Belgrade, Serbia, 2018-10)The introduction of cool and photovoltaic pavements in underground power cable engineering can contribute to reducing global warming and our dependency on fossil fuels. In this case, a cool or photovoltaic pavement would ... -
Thermal aging management for electricity distribution networks: FEM-based qualification of underground power cables
Klimenta, Jelena; Panić, Marija; Stojanović, Miodrag; Klimenta, Dardan; Milovanović, Miloš; Perović, Bojan (Thermal Science, 2022-03)It is well-known that there is no PLAN-DO-CHECK-ACT (PDCA) approach that is used by electricity distribution network operators and asset managers of power cable systems. Accordingly, this paper proposes a novel application ...
