Abstract

The criteria parameters allowing to estimate authentically the thermostability of dielectric liquids’ operational properties are chosen. Change of transformer oil’s operational properties during its interaction with polypropylene and polyethylenetereftalate films under the influence of the heightened temperature is analysed. The influence of morphological features of polypropylene film’s surface on the thermostability of the impregnated dielectric film is revealed. Low degree of the interaction between the polyethylenetereftalate film and transformer oil T-1500 is defined.
The reduction of the comparative light transmission coefficient illustrates the thermostimulated mutual dissolution in the system «polymer in the liquid». The consequent of this process is the degradation of the impregnated dielectric film components’ electrical characteristics. Analysis of kinetics of impregnating liquid’s light transmission can be informative and useful in comparative studies of various impregnated dielectric films, as well as for express diagnostics of impregnated film insulation during high-voltage pulse capacitors life tests
