Nuclear power plants contain a significant amount of fire load in form of electrical cables. The performance of the cables is interesting both from the fire development and system failure viewpoints. In this work, cable tunnel fires are studied using numerical simulations, focusing on the fire spreading along power cables and the efficiency of the water suppression in preventing the cable failu...

High Tc superconducting (HTS) cables and their application to develop a DC power transmission system with substantial advantages have been studied. Technical analysis of the HTS DC electrical power transmission system behaviours have been carried out with the HTS DC cable technology employed and the system models built. Index Terms -High Temperature Superconductor (HTS), HTS Cable, DC Transmiss...

In this work, we study the efficiency of developed OpenFOAM-based parallel solver for the simulation of heat transfer in and around the electrical power cables. First benchmark problem considers three cables directly buried in the soil. We study and compare the efficiency of conjugate gradient solver with diagonal incomplete Cholesky (DIC) preconditioner, generalized geometricalgebraic multigri...

Deterioration of the underground power cables insulation has been established to be caused by electrical, thermal and environmental stresses. With the degradation of dielectric strength of the insulation, the underground cables will not be able to function optimally or as planned. As a supplement to the existing dissipation factor and other conventional cable diagnostic measurements, the Decay ...

As U.S. power grid transforms itself into Smart Grid, it has become less reliable in the past years. Power grid failures lead to huge financial cost and affect people’s life. Using a statistical analysis and holistic approach, this paper analyzes the New York City power grid failures: failure patterns and climatic effects. Our findings include: higher peak electrical load increases likelihood o...

The ideal transmission cable exhibits little parasitic capacitance between individual internal cable conductors and also between the conductors and the cable shielding. However, transmission cables possessing high parasitic capacitance are becoming increasingly common in the glass coating industry. Cables designed for increased flexibility and reduced costs often provide minimal spacing between...

The proper channel modeling is essential for reliable data transmission at high rates over the power grid. This paper presents a finite element approach for the calculation of the electrical parameters needed for the simulation of low voltage distribution cables carrying high frequency communication signals. The results obtained by our approach are validated through measurements performed on va...
