dc.description.abstract Acoustic emission monitoring is often used in the diagnosis of electrical and mechanical incipient faults in high voltage apparatus. Partial discharges are a source of failure in power transformers and the differentiation from other sources of acoustic emissions is of the utmost importance. This paper reports the development of a new sensor concept - mandrel-based fiber optic sensors - for the detection of incipient faults in oil-filled power transformers, taking direct measurements inside a transformer. These sensors can be placed in the inner surface of the transformer tank wall, not affecting the insulation integrity of the structure, and improving fault detection and location. The applicability of these acoustic sensors in air, water and oil is investigated and the paper presents the promising results obtained, which will allow the industrial development of practical solutions. en
