Immersion photoacoustic spectrometer (iPAS) for arcing fault detection in power transformers

We report on the development of the first immersion photoacoustic spectrometer (iPAS) for arcing fault detection in power transformers. The spectrometer consists of a detection system and an all-optical photoacoustic sensing head mounted inside a small permeable chamber where dissolved C_2H_2 ...
