TY - JOUR A1 - Rohwetter, Philipp A1 - Eisermann, René A1 - Krebber, Katerina T1 - Random quadrature demodulation for direct detection single-pulse rayleigh C-OTDR N2 - We present a demodulation method that partially compensates for the nonlinear and random transfer function of fiber-optic direct detection coherent Rayleigh optical time-domain reflectometry (C-OTDR). Specifically, the proposed method is shown to improve the detection of small amplitude, high frequency dynamic optical fiber strain as it occurs in acoustic emission sensing. The method is applicable provided that the dynamic fiber strain to be sensed is known to affect a longer section of sensing fiber in a spatially homogeneous way. It is shown that this knowledge can be used to extract more quantitative information from the measured C-OTDR signal by averaging signal components from the affected fiber section in a suitable and efficient way. The theoretical basis of the method is developed and supporting experimental results are presented.

T1 - Acoustic emission from DC pre-treeing discharge processes in silicone elastomer N2 - Partial discharge in polymeric insulation of high voltage equipment causes cumulative damage that progressively deteriorates the insulation, leading to eventual failure. The electrical detection of related discharge current pulses may be challenged by electromagnetic interference from the environment. In such situations the detection of acoustic emission from partial discharge can greatly enhance its detectability, especially when electromagnetically immune fiber-optic acoustic sensors are used. During experiments involving such fiber-optic sensors that were specifically designed for the detection of partial discharge in elastomeric insulation, an unexpected type of acoustic emission was observed in silicone elastomer specimens with tip–plate electrode configurations and under DC electrical stress. We present and discuss experimental results that indicate space charge injection and subsequent spontaneous dynamical processes as the source of the detected acoustic emission. We use sensitive conventional partial discharge measurement instrumentation to show that the apparent acoustic efficiency of the processes leading to the observed acoustic emission is very high. Acoustic emission triggered by discharge events with individual apparent charge values of only a few femtocoulombs could be detected.

T1 - Dielectric strength behavior and mechanical properties of transparent silicone rubbers for HV cable accessories N2 - Modern optical partial discharge (PD) detection system based on fiber-optic sensors for PD on-line health monitoring in high-voltage (HV) cable terminations necessarily requires optically transparent or translucent insulation materials. The optically compatible silicone rubbers are the key to facilitate such innovative technology. In this work, AC 50 Hz dielectric strength Eb and mechanical properties of three types of commercially available silicone rubbers have been investigated. The investigations revealed that the translucent silicone rubber has a good mechanical performance but its Eb value is considered too low. However it is sufficiently good for use as base material for rubber stress cones. Unfortunately, its optical transmittance is poor compared to optically clear transparent silicones. On the other hand, the mechanical properties of transparent silicone rubbers do not comply with those demanded from push-on stress cones. In particular, their elongation at break is considered too low for that application. However they provide the Eb values of about 28 kV/mm to 29 kV/mm at 0.5 mm thickness, which are higher than those of the translucent type. Moreover, it was found that the post-curing process does not provide a positive impact on the ultimate elongation of silicone rubbers.

T1 - Sensitivity-enhanced detection of partial discharge in cable accessories using fluorescent polymer optical fibre-sensor N2 - A new fluorescent polymer optical fibre sensor (F-POF) has been tested in combination with different single photon counting modules in real-scale model of a translucent high voltage (HV) stress cone for the detection of inner partial discharges (PDs). In experiments with different artificial PD sources these sensors were capable to detect discharges with an apparent Charge down to the limit of a few hundred femto Coulombs even with an unfavorable sensor location. By combining the datasets of the electrical and optical PD measurement (coincidence window ±100 ns) it is possible to suppress background noise and to undoubtedly assign signals to real inner PD events. First results of an optical/optical coincident PD measurement (coincidence interval ±100 ns) including an AC phase-correlated filtering show several coincident photon counts in the ränge of 1-2 pC over the whole Observation interval, indicating the potential ofthis new alternative PD measurement and evaluation method.

T1 - Improved fibre-optic acoustic sensors for partial discharge in elastomeric insulations N2 - Partial discharge in elastomeric high voltage insulations is a major reason for device failure. The special challenges of the high voltage environment limit the use of conventional acoustic emission sensors. Fibre-optic sensors can cope with these challenges thanks to their optical sensing principle and the use of all-dielectric materials. In this contribution, improvements to a previously introduced design of ultrasonic fibre-optic acoustic partial discharge sensors for elastomeric insulations are presented. The improved performance of fibre-optic acoustic sensors in detecting AC partial discharge is demonstrated. Furthermore, their ability to detect low-level damage processes in elastomeric insulation under DC dielectric stress is shown to outperform the highly sensitive electrical detection method.

T1 - Verbesserte faseroptisch-akustische Teilentladungssensoren für elastomere Isolierungen T1 - Improved fibre-optic acoustic partial discharge sensors for elastomeric insulations N2 - Von uns entwickelte faseroptisch-akustische Sensoren wurden an Modellen für innere Teilentladungen (TE) in Silikonelastomer- Isolierungen erprobt. Bei 32 mm Abstand zu einer eingebetteten TE-Quelle wurde eine äquivalente Empfindlichkeit im Bereich weniger Picocoulomb scheinbarer Ladung erreicht. In einem Versuchsaufbau mit künstlicher TEQuelle, der durch Geometrie und Material ein Hochspannung-Aufschiebeelement simuliert, wurde bei akustisch gewollt ungünstiger Sensorplatzierung ein TE-Detektionslimit von 35 pC scheinbarer Ladung ermittelt. Neben der Leistungsfähigkeit der vorgestellten Sensoren in Bezug auf die Detektion von Wechselspannungs-TE wurde auch ihre Fähigkeit geprüft, Gleichspannungs-TE im elastomeren Isolierstoff zu detektieren. Dabei hat sich gezeigt, dass die akustische Methode bei Gleichspannung ein unerwartet empfindliches Werkzeug zum Aufspüren TE-behafteter Fehlstellen sein kann. N2 - Fibre-optic acoustic sensors developed by us for the detection of partial discharge (PD) in silicone elastomer insulation were tested using artificial embedded sources of PD. Few-Picocoulomb sensitivity was shown for a Separation of 32 mm between PD source and sensor. Additionally, sensor detectivity was investigated on a Setup simulating geometry and material of a real-scale push-on high voltage stress cone. An intentionally unfavourably placed sensor showed an equivalent detection limit of 35 pC apparent Charge. Besides testing sensing performance with respect to AC-PD, also the acoustic detection DC-PD in elastomeric insulation was investigated. This lead to the observation that the acoustic method is an unexpectedly sensitive tool for detecting PD -inducing defects in such materials under DC stress. T2 - 6.

T1 - Fluorescent fiber optical partial discharge sensor in high-voltage cable facilities N2 - New sensors for the detection of partial discharges (PDs) in high-voltage (HV) cable accessories are being de-veloped consisting of a fluorescent polymer optical fiber (F-POF) as sensing element. Depending on the fiber material F-POFs can be attached to and even integrated into the translucent silicone rubber insulation of HV cable terminations. As the embedment into the insulation material plays an important role, the sensor should not weaken the dielectric strength of the insulation material and should not be the origin of PD incidents. A sensor consisting of a commercial F-POF has been tested in the high-voltage lab regarding its PD detection ability un-der AC in comparison to a conventional electrical sensor. New silicone rubber F-POF (Si-F-POF) fiber models functionalized with coumarin dyes have been produced. The optical properties of these dye functionalized silox-anes are presented. These potential sensor fibers are highly flexible and might be embeddable at medium to high-voltage level. An additional way to further improve the level of PD light detection is to modify the translucent type of silicone rubber used in HV cable accessories in terms of optical transparency. In this context we present our first results of the optical and mechanical properties of new elastomeric transparent silicone materials specif-ically designed for the application as HV insulation materials in stress cones.
