| Abstract: | The time- and frequency-domain characteristics of transient electromagnetic disturbance caused by switching operations in substations were analyzed. Two methods were used in time-domain analysis. One was histogram and the other normality test. Appropriate procedures for the normality test were proposed and implemented by software. The method used in frequency-domain analysis was to compute overall envelope. These statistical characteristic analysis methods are showed to be of great value in analyses of the measured samples. |
