“…The PD is the fault characteristic phenomenon before the complete breakdown or flashover of GIS insulation, and it is also the early manifestation of GIS internal insulation defects, causing great hidden dangers to the safe and stable operation of GIS. Under the continuous action of PD, a variety of low-fluorine sulfides formed by SF 6 decomposition will react with H 2 O molecules, which will lead to the decomposition of the SF 6 gas which is difficult to reduce, and generate SO 2 F 2 and other SF 6 decomposition gases [4][5][6][7]. This will significantly reduce the insulation performance of SF 6 gas and accelerate the deterioration of GIS insulation, which may lead to sudden faults in the operation of GIS.…”

SF6 is a common insulating medium of gas-insulated switchgear (GIS). However, it is inevitable that SF6 will be decomposed due to partial discharge (PD) in GIS, which will cause hidden dangers to the safe and stable operation of equipment. Based on the DFT method, the two-dimensional nano-composite As-doped h-BN (As-BN) monolayer was proposed. By modeling and calculating, the ability of an As-BN monolayer as a specific sensor for SO2F2 (compared with an H2O adsorption system and CO2 adsorption system) was evaluated by parameters such as the binding energy (Eb), adsorption energy (Eads), transfer charge (ΔQ), geometric structure parameters, the total density of states (TDOS), band structure, charge difference density (CDD), electron localization function (ELF), sensitivity (S), and recovery time (τ). The results showed that an As-BN monolayer showed strong adsorption specificity, high sensitivity, and short recovery time for SO2F2 gas molecules. Therefore, the As-BN monolayer sensor has great application potential in the detection of SF6 decomposition gases.

“…At present, the optical detection methods of PD mainly use intensified charge-coupled device (ICCD), photomultiplier tube (PMT) and silicon photomultiplier (SiPM) [15]. The ICCD and PMT are not conducive to practical application due to their complex, large and costly detection systems.…”

Optical partial discharge (PD) detection is an efficient means of diagnosing the insulation status of power equipment. C4F7N/CO2 gas mixture is a very potential environmentally friendly SF6 substitute gas, and its PD optical characteristics need to be studied to guide the PD diagnosis of novel C4F7N/CO2 equipment. Therefore, this paper proposes a multispectral microarray detection technology, which can achieve high-sensitivity detection and PD diagnosis by simultaneously collecting the spectral characteristics of multiple bands. By setting up an experimental platform, the PD experiments of 4 typical defects in C4F7N/CO2 gas mixture with 5 different proportions and pure SF6 are carried out. Based on the analysis of PD multispectral features, the correlation between different gases and the difference between different defects are obtained. Finally, combining multispectral detection with t-distributed stochastic neighbor embedding (T-SNE) feature extraction algorithm, a PD diagnosis method that can adapt to both C4F7N/CO2 gas mixture and SF6 is proposed, which provides a reference for PD detection of novel C4F7N/CO2 equipment application.

“…Nowadays, the application of the fibre-optic sensor in partial discharge detection has received wide attention [7][8][9]. The fibre-optic ultrasonic sensor based on Fabry-Perot (FP) interference is the most commonly used fibre-optic sensor for oil-paper insulation partial discharge detection, which has several advantages such as its simple structure, high sensitivity, high-grade directivity, ease of multiplexing, etc [10][11][12][13].…”

In order to improve the sensitivity and accuracy of oil-paper insulation partial discharge detection by the fibre-optic Fabry-Perot (FP) ultrasonic sensor, this work studied the ultrasonic signal's frequency characteristics of typical oil-paper insulation partial discharges and the vibration characteristics of the FP sensor's diaphragm in the liquid environment. Based on the works above, a multifrequency FP sensor array is proposed, consisting of several FP sensors with different resonant frequencies to detect partial discharges. The experimental results show that the liquid environment has a significant effect on the vibration characteristics of the FP sensor's diaphragm, and the sensitivity and accuracy of partial discharge detection can be improved based on the multifrequency FP sensing array, which can also be applied in the pattern recognition and localisation of partial discharges.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
