To develop fiber sensors for targeted detection of relevant gas species (especially acetylene, for detection of discharge faults). Use AI/ML tools to map fiber data to identification of transformer
A single-fiber photoacoustic (PA) sensor with a silicon cantilever beam for trace acetylene (C2H2) gas analysis was proposed. The miniature gas sensor mainly consisted of a microcantilever and a non
An all-optical double-pass quartz enhanced photoacoustic spectroscopy (QEPAS) sensor for the detection of acetylene (C 2 H 2) at part-per-billion (ppb) levels was developed and
A fiber-optic acetylene gas sensor based on a microstructured optical fiber Bragg grating (MOFBG) is presented. The microstructured optical fiber (MOF) is specially designed to have a...
In this work, we report a simultaneous high-sensitivity and rapid-response acetylene (C 2 H 2) sensor enabled by a novel 3D-printed single-fiber photoacoustic probe.
A cantilever-enhanced fiber-optic photoacoustic sensor with pressure self-compensation is reported to address reduced detection accuracy in plateau regions for trace acetylene detection.
Several different material systems are investigated for detection of acetylene, as well as other hydrocarbons relevant to mineral oil degradation within transformers.
This article presents a novel multipoint acetylene (C2H2) sensing technology based on fiber-optic photothermal spectroscopy (PTS). The system employs a series of miniature PT sensors with
A fiber-optic acetylene gas sensor based on a microstructured optical fiber Bragg grating (MOFBG) is presented. The microstructured optical fiber (MOF) is specially designed to have a photosensitive
