In equation (1) R0, C0 and mj represent insulation resistance
and geometrical capacitance and the number of series elements
in any branch j. As the relaxation processes of different dipole
groups in the different isothermal sections, are assumed to be
exponential in nature, for simplicity the characteristics of the
series elements in Figure 6 are also assumed to be exponential
in nature and are of the form given in equation (2a). The values
of resistance and capacitance that models Zj(k,s) in Figure 6 are
related to parameters of Γj(k) by equation (2b).
