“…The stimulated fluorescent molecules in the fluorescent fiber will subsequently serve as the fluorescence launch center. When the fluorescence launch direction meets the total reflection conditions of the fiber core-packet layer interface [7,8,11], the fluorescence transmits forward along the fiber axial and finally shoots from the end face for detection. The inducted fluorescent light signal strength comes from the sum of each axial launch center, which accounts for the higher sensitivity of fluorescent fiber in testing weak light signals.…”

“…The fluorescent fiber was mixed with S m (S m 3+ ) Na 2 O-CaO-5SiO 2 glass, with absorption and emission spectra of approximately 400 and 650 nm, respectively. In 1991, Mangeret conducted sensitivity experiments for five different characteristics of optical fiber sensors with a needle-plate electrode defect [7]. The results show that the optical fiber sensor with the highest sensitivity can detect PD signals under a 5 kV test voltage and 2 μA current.…”

Based on the physical phenomena of optical effects produced by the partial discharge (PD) and on the characteristics of fluorescent fiber sensing of weak fluorescent signals, a PD measurement system using a fluorescent fiber sensor was designed. The main parameters of the sensing system were calculated, an experimental testing platform for PD simulation in the lab was established, and PD signals were then detected through ultra-high frequency (UHF) and optical methods under a needle-plate discharge model. PD optical pulses in transformer oil contained signal-peak and multi-peak pulse waveforms. Compared with UHF detection results, the number of PD pulses and the elapsed PD pulse phase time revealed a good corresponding relationship. However, PD signal amplitudes presented the opposite, thus indicating that PD UHF signals reflected pulse amplitude value, whereas PD optical signals reflected pulse energy magnitude. The n-u-φ three-dimensional distributions indicated that most of the PD signals concentrated in the nearby industrial frequency voltage peak value. Overall, the proposed fluorescent fiber sensing system design can be used successfully in transformer PD signal detection.

“…Our goal is to provide fibre-optic means of PD detection in so-called stress cones of cable accessories, either supporting an electrical measurement by providing a redundant, EMI-tolerant detection channel, or even working as a standalone detection method with good rejection of external electromagnetic disturbances. The detection of PD using fluorescent polymer optical fibres (F-POF) has already been demonstrated some time ago [1], but it has not been considered as an option to detect PD in cable accessories until recently. A proof-ofconcept was given by the authors of reference [2], where the detectability of PD in a prepared high voltage cable termination was demonstrated down to discharge levels of approximately Qapp ≈ 1-5 nC.…”

Elastomeric fluorescent POF for partial discharge detection: recent progress

et al. 2015

We present recent progress in our development of fibre-optic sensors for the detection of partial discharge (PD) in silicone cable accessories, based on detecting related low-level optical emission. We experimentally show that the sensitive optical detection of PD can dramatically enhance the performance of conventional electrical PD measurement in electromagnetically noisy environments, and that it can yield high sensitivity and specificity even when no synchronous electrical PD measurement is conducted. This is demonstrated using a real-scale model of a high voltage cable accessory with a surface-attached conventional thermoplastic fluorescent polymer optical fibre (F-POF) sensor. In order to increase light collection efficiency, as a prerequisite for a commercially competitive implementation using cost-efficient detectors, sensing fibres will have to be integrated into the silicone rubber insulation, close to the potential origin of PD-induced damage. This is the rationale for our efforts to develop elastomeric fluorescent sensing fibres, tailored to the requirements of the application. We discuss specific challenges to be tackled and report on the successful implementation of allsilicone rubber fluorescent POF, to our best knowledge for the first time.
