Different characteristics of thermally stimulated luminescence and conductivity in insulator are numerically calculated without the quasi-equilibrium approximation. The results are compared with corresponding results calculated using the quasi-equilibrium approximation. This comparison suggests that the quasi-equilibrium approximation is correct in the low temperature range of the thermally stimulated luminescence and conductivity curves for crystals which have the density of recombination centres higher than 10^{13} cm^{-3} and the recombination coefficient larger than 10^{-12} cm^{3} s^{-1}, or equivalently, for those with the initial free electron lifetime shorter than 10^{-1} s. For the high temperature range of the thermally stimulated luminescence and conductivity curves the quasi-equilibrium approximation gives correct results if the recombination centres density is higher than 10^{14} cm^{-3} and the recombination coefficient is larger than 10^{-12} cm^{3} s^{-1} or if the initial free electron lifetime is shorter than 10^{-2} s. The results of this paper show also that the so-called "first-order" shape of the thermally stimulated luminescence and conductivity curves is typical not of the weak retrapping only, but it can be obtained also for the strong retrapping.
