摘要：
In high voltage substations, secondary equipments placed in the switchyard and inside the control house can be highly sensitive to the transient electromagnetic disturbances due to switching operations. In order to evaluate transient electromagnetic environments (EME) and provide guidance for better immunity design of secondary equipments, it is necessary to measure and analyze these transient electromagnetic disturbances. During three new 500kV substations powered on, many transient electromagnetic disturbances were measured and recorded. Based on FFT transform, the analysis program was developed and used to analyze characteristics of the disturbances. The results are summarized. Comparisons with IEC61000-4 series standards are made and recommendations are given in this paper.
