THE METHOD OF MONITORING THE PARAMETERS OF TRANSFORMER OIL DURING ITS REGENERATION
(pp. 30-36)

Abstract. The dependences of the luminescence flux on the parameters of the GK transformer oil during its regeneration are investigated and a technique for its photoluminescent control is developed. In the process of regeneration, the radiating properties improve – the photoluminescence flux increases. Statistically reliable dependences of the photoluminescence flux on the oil parameters (acid number, breakdown voltage, moisture content and the tangent of the dielectric loss angle) were obtained. For the practical implementation of the photoluminescent control technique of transformer oil, it is advisable to use exciting radiation with a wavelength of 396 nm and flow registration in the range of 412…600 nm. The technique includes sample preparation, excitation and registration of luminescence, signal amplification and determination of the required parameter based on calibration characteristics. The proposed technique can be used to control the quality of oil during its regeneration, as well as during the operation of oil in high-voltage equipment.

Keywords: optical spectral diagnostics, transformer oil, regeneration, photoluminescence flux.
