“…The intensity of streamer discharge is very high, and it can convert oxygen into zones, which is also recognized as the working principle of the DBD reactor. Corona discharge and glow discharge are usually used for negative discharge [11][12][13][14][15][16]. Their discharge intensity is lower than that of a streamer.…”

Discharge mode is an important parameter for ozone synthesis by dielectric barrier discharge (DBD). Currently, it is still challenging to stably generate glow discharge with oxygen at atmospheric pressure. In this paper, a DBD reactor with a layer of silver placed between the electrode and the dielectric layer (SL-DBD) was developed. Experimental results show that both streamer and glow corona discharge were stably generated under sinusoidal excitation with a 0.5 mm discharge gap in a parallel-plate DBD, due to the increased electric field strength in the discharge gap by the silver layer. It was also found that, in the SL-DBD reactor, glow corona discharge enhances the discharge strength by 50 times. The spectral peak of O at 777 nm in SL-DBD is increased to 28,800, compared with 18,389 in a reactor with a streamer only. The SL-DBD reactor produces ozone with a concentration of as high as 150 g/m3 and shows good stability in an 8 h durability test.

“…Therefore, need of the hour is to specify advanced in-situ degradation quantification methods for ABCs allowing energy companies to undertake pre-emptive maintenance, that is, before any untoward power shutdown occurs. A novel diagnosis scheme for ABCs installed in low voltage distribution networks in coastal areas, based on partial discharge evaluation has been presented by the authors in earlier publications [4,7]. The temperature distribution generated in the ABCs' insulation is another parameter that has the potential to evaluate the degree of insulation damage as the cable deteriorates with time in coastal environment.…”

“…Despite abovementioned benefits, the reliability of in-service ABCs, when subjected to changing climatic conditions, is not precisely known yet [6]. ABCs are reported to have a shorter lifespan when subjected to severe environmental conditions in coastal areas [4,7]. The combined effect of high solar radiation intensity, high moisture content, and heavy electrical loads in coastal metropolises, stresses the insulation of ABCs.…”

Of late, cross-linked polyethylene insulated aerial bundled cables have replaced conventional copper conductors being resistant to electricity pilferage, offer lower maintenance costs and reduced power losses. However, in coastal areas, aerial bundled cables experience frequent insulation breakdown causing sudden cable failures leading to unexpected power shutdowns. Condition monitoring, employing sophisticated diagnostic techniques, has thus become a major requirement of the energy sector. The reported research work utilizes infrared thermography as one such candidate NDT technique. A novel framework is proposed to investigate the progressive shift in the statistical parameters of the temperature distribution in aerial bundled cables' insulation, as it degrades over time. The cumulative distribution function of pixel intensity data from a healthy/ operational aerial bundled cable is first compared with a reported failed aerial bundled cable. A prominent difference in 0.9 cumulative distribution function values is observed in the temperature distributions. Therefore, 0.9 cumulative distribution function values are used for degradation quantification with respect to ageing. Degradation rates are then computed using periodically acquired thermographic data from operational aerial bundled cables, installed at two different locations in a coastal region, each subjected to different marine climate. The proposed technique proved effective in degradation rate assessment of insulation of operational aerial bundled cables. Consequently, the results achieved can also be utilized for remaining useful life prediction of these cables.
