A numerical methodology for thermal analysis of buried power cables in presence of heat and moisture migration in the surrounding soil is presented. The governing equations are solved via a finite volume methodology and both cable and soil are incorporated in the problem formulation. The developed pr...
3.Measurement cable (optical) depth of the buried 4.Current detection signal cable; skin damage / shield ground faults 5.Detecting shortcircuit overhead line or touch the ground fault; determine the wet part of the cable to Positioning Indicator cable...
The heat resistance of the soil surrounding underground cable ducts is usually large, and the path of the heat through the soil is not simple, especially when there are several adjacent ducts. This heat resistance and the path of the heat flow may be determined graphically, but except in the...
Left: An underground three-phase electrical cable. Right: Cross-sectional schematic of a buried three-phase cable. The alternating current passing through the cable results in a time-varying magnetic field, which causes induced currents in the cable as well as in the surrounding metal sheaths an...
