Transformer Oil Quality Diagnostic Using Spectroscopy Techniques - a Review

Transformer serves as a vital component in the electrical energy supply system. In order to have an uninterrupted power supply, it is essential to timely monitor the condition of the transformer. A transformer has many components, out of which the transformer oil is one of the most crucial. It provides insulation and keeps the transformer cool. With ageing, the quality of the transformer oil degrades, and it loses its insulation properties that become a threat to the supply system. Optical Spectroscopy has gained a lot of attention in monitoring the quality of transformer oil in the past few years for various advantages. This paper reviews some of the commonly applied Spectroscopy techniques to monitor the various components of transformer oil by which we can predict the quality of the oil

Intensity-based Macro-bend Plastic Optical Fiber Sensor Using Raspberry Pi Platform

This paper presents an optical fiber sensor-based instrumentation system to measure the light intensity due to different refractive indices. The proposed sensor system consists of (i) He-Ne Laser as a source (ii) Fiber optic cable (iii) CCD camera to capture the intensity (iv) Raspberry Pi using phyton for processing. The optical fiber is bent into different radius and the intensity is captured every time the fiber is bent by the CCD camera. The Raspberry Pi use the phyton codes to process the captured intensity and plot it in the Gaussian curve. This sensor can be used for sensing the intensity of different solutions with different refractive indexes
