CALCULATION OF THE RESIDUAL RESOURCE OF INSULATION OF WINDS OF OIL TRANSFORMER
In the article the technique of calculation of the relative wear of winding insulation in oil transformer. Surveyed existing three-phase oil transformers are connected in electrical equipment. In the study, the calculated and experimental data, which can predict the residual life of the transformer insulation. Depending on the calculation of a residual resource to make timely inspections, repairs and replacement of equipment. As a result of the calculation of the residual life of the transformer required data of daily load, oil temperature and the environment, the thermal state of the winding NNT not only in the current, limited period and for a fairly long period of measurements.
