Abstract

See full text

An inspection probe for directly measuring a transmission spectrum of a solvent oil in a transformer includes a tube having a plurality of apertures spaced along a side of the tube to allow oil to pass therethrough, and first and second optical collimators disposed at opposing ends of the tube. The first and second collimators are aligned by the tube such that incident light is transmitted through the first collimator, the tube, and the second collimator to a spectrometer.
