FENG Liping1, LI Yefeng1, CHEN Chaohui2, et al. EVALUATION METHOD FOR RESIDUAL SERVICE LIFE OF TRANSFORMER OIL IN OPERATION[J]. Thermal power generation, 2011, 40(5): 27-29.DOI:
Through continuous and unceasing test and measurement of interfacial tension of new transformer oil and transformer oil in operation during the aging process
and test of the induced period to oxidation under temperature of 100 ℃
110 ℃ and 120 ℃
the results of test have been regressively processed
an evaluation method in laboratory for residual service life of transformer oil in operation being put forward
its evaluation model being N=t÷{(T-t)÷n}.The practical application of said evaluation method shows that the result of evaluation tallies well with the actual residual service life of transformer oil.
