Analysis of By-Products of N2-SF6 Gas Mixtures Sparked under Inhomogenous Field Conditions [PDF]
, 2004 A vast data on formation of by-products due to arc and spark decomposition of SF6 is available in literature [1–10]. But experimental work relating to N2 - SF6 gas mixtures is limited. In view of increasing application of gas mixtures, it is essential to

A Review on Real-Size Epoxy Cast Resin Insulators for Compact High Voltage Direct Current Gas Insulated Switchgears (GIS) and Gas Insulated Transmission Lines (GIL)—Current Achievements and Envisaged Research and Development [PDF]
Energies, 2020 Due to the ever-increasing demand for electricity in the one hand and the environmental constraints to use clean energy on the other hand, the global production of energy from remote renewable sources, particularly from large hydropower plants and offshore wind farms and their connection to the grid are expected to grow significantly in the future ...

High Voltage, Volume 11, Issue 2, Page 556-563, April 2026.ABSTRACT The breakdown characteristics of the novel eco‐friendly insulating gas CF3SO2F are fundamental to the design of gas‐insulated equipment. In this paper, the gas mixture parameters for CF3SO2F were optimised for different ambient temperatures in order to ascertain the insulation performance and liquefaction temperature constraints.

High Voltage, Volume 11, Issue 1, Page 192-200, February 2026.ABSTRACT Surface discharge is a typical fault type in electric power equipment. High temperature in long‐term operation can easily lead to ageing of materials, resulting in changes in surface characteristics and surface discharge faults. In this paper, a method of surface discharge identification of silicon rubber (SiR) based on spectral detection ...

Chromatic processing for feature extraction of PD-induced UHF signals in GIS
Global Energy Interconnection, 2020 Partial discharge (PD) detection is an effective means of discovering insulation faults in gas-insulated switchgear (GIS). One of the most extensively used methods in PD detection has historically been the ultrahigh frequency (UHF) method.

JE-Unisla, 2021 This paper analyzes the effect of the presence of foreign particles on an equilateral arrangement of 3 phase gas insulated switchgear (GIS) insulation equipment. Gas Insulated Switchgear (GIS) that uses SF6 insulation, partial discharge will occur as the insulation ages and there are several other factors that affect the insulation.

Nondestructive Measurement of Residual Stress on Epoxy Insulators Using Thermoelastic Method
High Voltage, Volume 11, Issue 1, Page 274-283, February 2026.ABSTRACT Residual stress is inevitable in epoxy insulators, which easily leads to small cracks and even insulation breakdown during the operation of gas‐insulated transmission line (GIL)/gas‐insulated switchgear (GIS). This study proposes a nondestructive method to measure the residual stress on epoxy insulators using thermoelastic effects.
