In order to avoid abnormality before the replacement of the transformer
it is extremely important to identify the devices’ degradation statuses. It is considered that the furfural is the product which is only generated by insulating paper aging.The relationships between the furfural concentration and the operating time of 135 field transformers in Hunan province is analyzed in the paper. Reliability
problem and the improved method of paper insulating aging identified by furfural concentration in operated transformer are discussed.
