... electric power. Design/methodology/approach The use of power cable system responses to power line carrier signals are proposed to conduct the required signal analysis for damage location purpose. This technique is based on the fact that the water tree degradation in power cables can make the system...

... enables us to understand the physical nature of the device. Thermal equilibrium In the above equations, E = ‐ —Ψ stands for the electric field, v is the mean velocity and T is the scaled temperature (the usual temperature in Kelvin T ← k_bT...

... to derive the analytical expressions for the device noise parameters F₀, Γ₀ and N in terms of the electrical elements associated with the basic equivalent circuit of an HEMT. Analyses such expressions to establish some fundamental relationships, as well...

.... The direct solutions for capacitance and inductance can be used to derive expressions for the forces and torques within the system, using the principle of virtual work. The finite element method[ 1 , 2 ] has gained wide popularity as a flexible tool for determining the field distribution of electrical...

...G. Aiello; S. Alfonzetti; S. Coco; N. Salerno Charge iteration is an iterative procedure for the finite element computation of unbounded electrical fields, created by voltaged conductors. It makes use of a fictitious boundary, enclosing all the conductors, on which the electrical potential is first...

... element method. Equations (1) and (6) together with the constitutive relations (7), (8), (10) constitute the differential equations that govern the elastic waves in piezoelectric media. Both mechanical and electrical boundary conditions need to be prescribed on the boundaries in order...

...G. Chen; A.E. Davies The electric stress profiles of a needle‐plane electrode system used in the laboratory for investigation of tree initiation and growth have been studied. Results from analytical solution based on a hyperboloid shaped needle tend to differ from those from experiments. One reason...

... as a return path for fault currents and is an outer screen for the electric field. Whereas the conductor is usually copper or aluminium, owing to costs the sheath is made from aluminium, lead or steel (in the case of gas insulated systems). The sheath material must be able to carry fault and impulse currents...
