| Abstract: | In order to reduce the life test time of solid dielectric materials and to make the experiments feasible and effective, a method of life time test with cut-tail samples and specimens divided into groups is developed and the exponential distribution parameter estimation is discussed in this paper. Simulation experiments were completed 4with the aid of Monte-Carlo Method to investigate some important aspects such as the necessary number of specimens, errors of statistical characteristic values obtained, test times and expenses for specimens, etc. Practical experiments were performed to support the results obtained from simulation experiments. |
