Analysis of underground cable ampacity considering non-uniform soil temperature distributions

Load cycling of underground distribution cables including thermal soil resistivity variation with soil temperature and moisture content

“…, and v 3 − are denoted as Eigen vector. Constants of the equation are c 1 , c 2, and c 3 can be calculated using (7) by the determination of the temperature at steady state (∞), and at steady state, the effect of capacitance in Fig. 1a is neglected and determination of the initial temperature (0) at each load cycle is calculated.…”

“…Thermal analysis of underground cables is an important theme in these days to the power cable engineers, to avoid cable damage. Many studies discuss the thermal analysis of underground cables using analytical and numerical methods, and experimental investigation was performed [6][7][8][9][10][11][12][13][14][15][16][17][18]. Thermal analysis of underground power cables using two-dimensional finite element method is reported by the authors in [19][20][21].…”

Rapid Transfer Matrix-Based Calculation of Steady-State Temperature Rises in Cable Ducts Containing Groups of Three Phase Cable

“…According to the electrical circuit analysis method, the nodal voltage is decided by the reference point and source. Therefore, Eq (3) can realize the calculation of temperature rise under different ambient temperature and the real temperature of cable core is the sum of temperature rise and ambient temperature [22].…”

On‐line monitoring device for dry zone formation in the soil surrounding underground power cables

“…Numerical simulation to study the heat dissipation processes in the underground power cable, thermal analysis of power cables are investigated by the authors of [11,12,19]. Theoretical models to calculate steady-state, dynamic ampacity and emergency current ratings of underground power cables are discussed in [20][21][22][23][24][25][26][27].…”
