“…Additionally, the time from arc generation to ignition was measured using the UV detection system. Further, a Hamamatsu UV detector tube with 185-to 260-nm response spectrum was employed [12], [13]. The UV detector is powered by the driving circuit and converts the UV signal into an electrical signal to ensure more reliable and accurate results during detection of invisible discharge phenomena such as UV radiation, flames, and corona discharge.…”

Unintentional arc faults due to damaged power line cords and loose connections can cause serious fires; thus, they are a safety hazard in residential areas. Therefore, arc fault circuit interrupters are being increasingly used in homes to protect against arcs that may cause fires. In this paper, we analyzed the ignition characteristics of series arcs on the basis of load current. Furthermore, we recommended suitable arc clearing times through characteristics analysis in the Korean residential electric environment. We determined the arc clearing time via the carbonized path arc clearing time test using an ultraviolet signal detecting system according to the test method of the UL 1699 standard. In the experiments, heat-resistant indoor PVC insulated (HIV) wires, which is a type of residential electrical wire, were used as the wire specimens.Index Terms-Arc clearing time, arc fault circuit interrupters (AFCIs), carbonized path, heat-resistant indoor PVC insulated (HIV) wire, ignition, series arc fault, ultraviolet (UV) sensor.

“…According to these spectral characteristics, several detection methods are applied. The widely used infrared imaging methods necessitate a temperature gradient between the destination object and the background environment, which causes significant interference from Sunlight [9]. Fortunately, near the Earth's surface, the absence of solar-blind UV light from the Sun can significantly reduce the influence of solar irradiation [10,11].…”

“…Ternary oxide systems, such as In 2 Ge 2 O 7 , Zn 2 GeO 4, and ZnGa 2 O 4 [19][20][21], are more chemically and thermally stable than binary wide-bandgap materials (ZnO, SnO 2 , and TiO 2 ) [22][23][24][25], and are more competitive candidates for solar blind UV detection due to their larger bandgap and higher photon energy thresholds [26]. Additionally, the two channels of the UV/VIS bi-spectral image system are supposed to obtain UV and VIS images simultaneously [8,9,12], so that the fused image can provide accurate location information. However, most reported UV/VIS bi-spectral PDs only have one single channel towards a broadband spectrum of both UV and VIS light [27][28][29][30][31].…”

Various spectral bands provide different types of information, and information enhancement could be achieved by selective fusion of different spectral bands. The fused solar-blind Ultraviolet (UV)/Visible (VIS) bi-spectral sensing and imaging can provide the precise location of UV targets in virtue of VIS background, which has been increasingly promoted. However, most reported UV/VIS bi-spectral photodetectors (PDs) only have one single channel towards a broadband spectrum of both UV and VIS light, which cannot distinguish two kinds of signals, hindering the image fusion of bi-spectral signals. This work demonstrates the solar-blind UV/VIS bi-spectral PD based on vertically stacking perovskite of MAPbI3 and ternary oxide of ZnGa2O4 with independent and distinct response toward solar-blind UV and VIS light in a single pixel. The PD exhibits excellent sensing properties with an Ion/Ioff ratio of >10^7 and 10^2, detectivity of >10^10 and 10^8 Jones, and response decay time of 90 μs and 16 ms for VIS and UV channels, respectively. The successful fusion of VIS and UV images suggests that our bi-spectral PD can be applied in the accurate identification of corona discharge and fire detection.

“…That is, when high-voltage equipment discharges are caused by small defects in the insulation component, the difference in electric field strength could release an emission in the range of UVC radiation. Accordingly, the analysis of UVC signals is a reliable method for a promptly online substantiation of insulator defects in a high-voltage apparatus. , Therefore, UVC PDs have drawn immense research attention for not only fast realizing UVC overexposure but also numerous applications relevant to UVC leakage.…”

Flexible and self-powered photodetectors (PDs) have become one of the most popular topics, attracting researchers in the field of optoelectronic applications. In this study, for the first time, we demonstrate partial discharge detection in a practical environment with a prepared flexible device. Poly(vinylidene fluoride) (PVDF) is utilized as a highly transparent material in the UVC region, to create a flexible substrate with the antihumidity property. A detector that uses a mixed-halide perovskite (FAPbI3)1–x (MAPbBr3) x as the photoactive material is constructed in a vertical structure on the as-prepared hydrophobic PVDF substrate. The fabricated device exhibits good performance with a fast response speed (t rise = 82 ms, t fall = 64 ms) and a high detectivity of 7.21 × 1010 Jones at zero bias under 254 nm UV illumination, along with superior mechanical flexibility at various bending angles. Additionally, the air-exposure stability and reproducibility of the as-prepared device exhibit almost the original performance after 6 weeks of storage. For practical applications, we demonstrate a facile and sensitive detection for UVC leakage from a germicidal lamp and simulated a partial discharge system using our PD without energy consumption. These results indicate that this new approach may be useful and convenient for the detection of the partial discharge as well as for several practical applications.
