This paper proposes closed-form expressions for the calculation of the ground-return
impedance and admittance of underground cables. The proposed expressions are shown to …

This paper proposes small-argument approximations for two closed-form equations that
were recently derived for the calculation of the ground-return impedance and admittance of …

This paper proposes to represent the frequency dependence of soil parameters via a
rational approximation in the frequency domain. Two types of causal soil models were …

In this paper, Vance's closed-form approximation for the ground admittance of a single
underground cable is extended to represent three-phase underground cable systems. The …

The computation of sea/seabed-return distributed parameters of subsea cables is a relevant
topic due to the growing importance of submarine connections. This article presents for the …

Typically, the modeling of underground cables systems for electromagnetic transient
simulations is carried out disregarding the effects of the ground return admittance. However …

Nowadays many researchers are focusing on on-line condition monitoring of highvoltage
(HV) insulated cable systems to prevent failures. With the aim of reducing the current …

No estudo de sistemas de potência é imprescindıvel o emprego de parâmetros fısicos que
sejam compatıveis com oscilaçoes cuja frequência está associadaa natureza do fenômeno …
