MONITORING AND REPAIR OF INDUSTRIAL POWER TRANSFORMERS TECHNICAL CONDITION
One of the most important tasks of modern industry is to maintain operable force oil-filled equipment. The basis of such equipment make up the oil-filled transformers. Damage to power transformers arise during the operation and the main reason is the lack of efficiency of currently accepted diagnostic system. One of the promising methods to assess the technical condition of the power transformers is a spectral method based on the analysis of the relationship generated motor drive parameter of higher harmonic currents of the technical condition and operation of the equipment. The challenge is the need for a transformer to ensure that environmental and fire safety. Short circuit losses occurring in the transformer during normal operation, lead to physical and chemical degradation of oil. Decomposition of transformer oil, in turn, entails the formation of a working volume of gas dissolved in oil. Therefore, necessary for monitoring systems for stationary control and analysis of the dissolved gases in the oil.
