Development of ± 550 kV DC GIS Basin Insulator

High Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

Analisis Histologi Pelepah Daun Kelapa Kopyor Hibrida (Kopyor dalam Sinumpur (KDS) × Kopyor Genjah Kuning Sinumpur (KGKS)

Proceedings Series on Physical & Formal Sciences
Perbaikan kualitas kelapa kopyor khususnya melalui persilangan belum banyak dilakukan. Di samping memerlukan waktu yang cukup lama, metode deteksi keberhasilan persilangan juga belum banyak dikembangkan. Saat ini metode morfologi sebagai alat deteksi keberhasilan persilangan memiliki keterbatasan sedangkan metode molekuler relatif mahal dan membutuhkan

Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

High Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Decoding KGK VI Population Movements: Strontium Isotope and Proteomic Insights from the Gumelnița Site (Romania)

Abstract The Kodjadermen-Gumelnița-Karonovo VI human group (KGK VI) reached its maximal extension around 4500 BC, covering a large area comprised between southern Ukraine and northern Greece. Afterward, its distribution gradually receded, before vanishing altogether at the end of the fifth – early fourth millenniums BC.

An Improved Method for Calculating the Radiative Cooling Heat Dissipation Power of an Oil‐Natural‐Air‐Natural Transformer

High Voltage, EarlyView.
ABSTRACT Radiative cooling holds potential for outdoor transformers in operation due to its zero‐energy consumption and high adaptability and has demonstrated effective heat dissipation in simulations of small distribution transformers. Accurate calculation of the transformer temperature rise and the radiative cooling effect is crucial for practical ...
