The System of Transformer Oils Laser Control by the Method of Sensing Through a Cuvette

The paper represents system of transformer oils control by the method of environment laser sensing through a cuvette. Transformer oil acts as a dielectric active medium. Measurement of the indicators is based on the resonance examination of the laser beam. The method of constructing laser photometers for evaluation of transformer oils quality is considered. The use of photometers is tested on experimental stands in the production conditions of power plants (where the oils are used for heat transfer during cooling of transformers).
