Today, there are many attempts to introduce the Internet of Things (IoT) in high-voltage
systems, where partial discharges are a focus of concern since they degrade the insulation …

Crucial commercial and space applications require the detection of broadband ultraviolet
(UV) rays spanning from UV-A to UV-C. In this study, the authors demonstrate a broadband …

Due to the increase in electrical power demand, future more electric and all-electric aircraft
designs will operate at higher voltage levels compared to current aircraft. Due to higher …

Insulation faults in high-voltage applications often generate partial discharges (PDs)
accompanied by corona activity, optical radiation mainly in the ultraviolet (UV) and visible …

The principal objective of this study is to improve the diagnostics of power transformers,
which are the key element of supplying electricity to consumers. On Load Tap Changer …

Electric arcing is a common problem in DC power systems. To overcome this problem, the
electric arc detection algorithm has been developed as a faster alternative to existing …

The article presents a comparison of the spectra of electromagnetic radiation emitted by an
electric arc. The spectrum ranges from ultraviolet through visible light to near infrared …

The electrical discharges are, among others, accompanied by the emission of
electromagnetic waves of various frequencies. We studied this emission for the surface …

Transformer explosions and fires are the most dangerous consequences of transformer
faults. As protection each transformer is equipped with a Buchholz relay (BHR), which …

Transformer explosions and fires are the most dangerous consequences of transformer
faults. Besides the financial loss, consequences are often environmental pollution, fires and …
