Modern power systems face several problems at frequencies above the range of traditional
stability studies due to the increasing penetration of power electronic devices. This …

This paper investigates the influence of the ground admittance correction and the frequency
dependence of ground conductivity and permittivity on the simulation of electromagnetic …

When a transformer is subjected to very fast front transients, the penetration of the magnetic
flux into the core becomes, in general, negligible. To represent this phenomenon, it is …

Fast front pulses from lightning and switching conditions produce transient overvoltages and
dielectric stresses that can result in premature deterioration or failure of transformer …

Fault location plays a pivotal role in expediting the restoration of systems after faults.
However, the necessity for rapid fault isolation in multi-terminal direct current (MTDC) …

This paper presents the practical application of frequency domain methods to perform
detailed electromagnetic transient analysis on very large multi-phase power distribution …

For the analysis of power system transients in overhead transmission lines and underground
cables, a common assumption is related to the quasi-TEM (transverse electromagnetic) …

This paper describes two network models which allow several harmonic and
electromagnetic transient analysis, being, therefore, more flexible than conventional ones. In …

Accurate fault calculation is vital for the parameter design and protection research of high-
voltage DC (HVDC) grids. This paper proposes a general method to calculate short-circuit …

Toroidal transformers are currently used only in low-voltage applications. There is no
published experience for toroidal transformer design at distribution-level voltages. This …
