STUDY OF SOME INSULATING OILS AGING BY THERMAL CYCLING
The By gravimetric measurements and coupled thermal analysis techniques (DTG+TG+DTA) the aging of different sorts of insulating oil was studied by thermal cycling between -400C and 850C. The experimental results showed that, during the thermal cycling of the investigated mineral oils, their co...

description |
The By gravimetric measurements and
coupled thermal analysis techniques (DTG+TG+DTA)
the aging of different sorts of insulating oil was
studied by thermal cycling between -400C and 850C.
The experimental results showed that, during the
thermal cycling of the investigated mineral oils, their
composition changes due to the volatilization of the
volatile fractions (mass losses between 3.9% and
5.8%), unlike the investigated vegetable oil that
showed a mass increase of approx. 0.66%. It has also
been found that the mineral oils can be ensure a safe
operation, without significant changes up to a
maximum of 1000C, as long as investigating vegetable
oil can be used without degradation risk up to 2000C. |
