Diagnosis of transformers of electrical complexes using non-contact laser vibrometers

TARGET. The purpose of this work is to improve the method vibration control active part a power transformer by fractal analysis its signal. Fractal magnitude-time characteristics quantitative assessment degree "jagged" signal transformer. For assessment, coefficient (FAC) was introduced based on determination dimension Hausdorff-Besikovich method. To test developed application, non-contact laser measuring diagnostic complex (MDC) with software LabVIEW, ImageJ and Python. Experimental studies technical condition TSZ 16 were carried out basis using LCIK, CFA windings magnetic circuit single determined, level for impulse elements determined. METHODS. makes it possible during operation under voltage, which switch from planned system repairs taking according current condition. RESULTS. improved tested noncontact voltage CONCLUSION. An determine an energized possibility automatically obtaining decision condition, as well use statistical methods processing analyzing signals received
