Sažetak
The paper describes an analytical approach to the issue of skin effect on current or current density distribution over the cross-section of the tube type conductors. The same cross-section can analogical be taken for any multi-layer conductor of different construction designs. Due to the skin effect, the current flows towards the conductor surface, the result being an uneven current distribution over the conductor cross-section. A mathematical algorithm is given enebling determination of the current density distribution over the tube type cross-section. It is computed with the Maxwell's equation from the theory of electromagnetic fields and by using Bessel's functions of the first order. With thus implemented model the authors developed an algorithm for the current determination with consideration of the skin effect in the multi-layer ACSR 490/65 conductor and optic cable of the type OPGW. The result show the current density distribution in individual layers of ACSR 490/65 conductors with adiabatic heating at 1000 Aeff in the stady state. The same applies to the OPGW cable at the short-circuit current of 15.4 kAeff at the duration of 1s.
