Abstract
The physical meaning of the empirical Okamoto equation, which has been used to verify the front shape of return voltage measured values, is correctly analyzed in relation to the dipole distribution in dielectrics. It is shown that there is a strong relation between the parameters of this equation and the shape of the distribution function of relaxation times. The measuring parameter (short-circuit time) also has a great influence of the equation parameters. According to the obtained theoretical results an interpretation of dielectric aging can be formulated
