Distribution transformer efficiency vs. aging
Distribution transformer efficiency vs. aging
(OP)
I couldn't find any curve/relation between distribution transformer aging and reduction in efficiency. Oil degradation and winding insulation degradation are main causes of aging incerasing the failure risk. Any clue about efficiency vs. aging?

The earliest soft magnetic material was iron, which contained many impurities. Researchers found that the addition of silicon increased resistivity, decreased hysteresis loss, increased permeability, and virtually eliminated aging.
I found another reference that stated that transformer steel is made with very low levels of carbon. Carbon inclusion was stated to promote ageing.
And this;

"Ageing always occurred in transformers built before the introduction of silicon steel (about 1910)

Should I worry about oil at that voltage level?
