The effect of paper properties on the temperature and stress dependence of the resistivity of impregnated laminates

The resistivity of papers impregnated with a low viscosity fluid has been measured from 20 /spl deg/C to 800 /spl deg/C. The data have enabled the temperature (/spl alpha/) and stress (P) coefficients to be established. Sensitivity analysis shows that the most significant coefficient for determining the electrical stress distribution is the temperature coefficient.
