The reliability of power delivery can be profoundly improved by preventing wildlife-related power outages. This can be achieved by insulating electrical substation components with non-conductive covers. The manufacture of custom-built covers requires as-built models of the salient components. This study presents new, automated methodology to recognize key components of electrical substations fr...

In railway power supply systems using AC frequencies lower than the public grids of 50/60 Hz, high voltage AC overhead transmission lines in railway grid frequency are used as one measure of strengthening the systems. An increased resistance to overhead high voltage AC transmission lines, may motivate cables for future railway power systems. With the frequency of 50/60 Hz, reactive power produc...

Nowadays, with the development of industries, electrical types equipment are used and applied widely for many different purposes. One them is use power cables to transmit electricity over long distances, from generator stations consumers. Local global fields usually created by extensive presence currents following in general underground particular. Not only causes directly some unwanted effects...

With power systems switching to smart grids, real-time and on-line monitoring technologies for underground distribution power cables have become a priority. Most distribution components have been developed with self-diagnostic sensors to realize self-healing, one of the smart grid functions in a distribution network. Nonetheless, implementing a real-time and on-line monitoring system for underg...

The backfill materials around under-ground power cables affect the maximum current carrying capacity of these cables. Usually backfill soils around under-ground power cables lose their moisture content, forming dry zones around the cables and leading to an increase in the thermal resistance and decreasing in maximum current carrying capacity. But according to the results of the experimental wor...

In the field of energy transport, High-Voltage DC (HVDC) technologies are booming at present due to the more flexible power converter solutions along with needs to bring electrical energy from distributed production areas to consumption sites and to strengthen large-scale energy networks. These developments go with challenges in qualifying insulating materials embedded in those systems and in t...

Abstract As the main electrical equipment of offshore power grids, optical fiber composite submarine cables undertake task transmission and data communication. In order to ensure proper functioning cable, it is necessary analyze working state identify fault event. This paper proposes a detection method for cables, that is, VMD self-attention-based Bi-LSTM model. First, we use ANSYS software gen...
