Series Arc Fault Detection and Localization in DC Distribution System
Qing Xiong,Xianyong Feng,Angelo L. Gattozzi,Xiaojun Liu,Linzi Zheng,Lingyu Zhu,Shengchang Ji,Robert E. Hebner +7 more
TL;DR: It is determined that a Rogowski coil could be constructed with adequate bandwidth to cover the relevant frequency band of 1 kHz–1 MHz and found that the amplitude of the pulse and the difference in the integrated fast Fourier transform of the current signal are well correlated with the series fault.
Journal ArticleDOI
Arc Fault Detection and Localization in Photovoltaic Systems Using Feature Distribution Maps of Parallel Capacitor Currents
Qing Xiong,Xiaojun Liu,Xianyong Feng,Angelo L. Gattozzi,Yuhang Shi,Lingyu Zhu,Shengchang Ji,Robert E. Hebner +7 more
TL;DR: In this article, an arc fault detection and localization approach using parallel capacitors is proposed using discrete wavelet transformation on the capacitor currents and the distributions of their amplitudes, frequency spectrums, and polarities.
Journal ArticleDOI
Detecting and localizing series arc fault in photovoltaic systems based on time and frequency characteristics of capacitor current
Qing Xiong,Qing Xiong,Shengchang Ji,Xiaojun Liu,Xianyong Feng,Fan Zhang,Lingyu Zhu,Angelo L. Gattozzi,Robert E. Hebner +8 more
TL;DR: In this article, a detection method for series dc arc faults in a photovoltaic (PV) system based on time and frequency characteristics of a parallel capacitor current is proposed.
Journal ArticleDOI
Electromagnetic Radiation Characteristics of Series DC Arc Fault and Its Determining Factors
Qing Xiong,Shengchang Ji,Xiaojun Liu,Xining Li,Lingyu Zhu,Xianyong Feng,Angelo L. Gattozzi,Robert E. Hebner +7 more
TL;DR: In this paper, a fourth-order Hilbert fractal antenna is used to detect the EMR signals generated by the series dc arc, and the amplitudes of EMR pulses at the arc initiation moment were measured, and fast Fourier transform was used to analyze the characteristics of the frequency spectrums.
Proceedings ArticleDOI
A Raman spectroscopic study of bulk and surface ageing phenomena in polyethylene
TL;DR: In this paper, low density polyethylene (LDPE) films were subjected to a range of electrical stresses, and the results indicated that erosion involves fragmentation of the LDPE and the formation of volatile by-products.
