Measurement and characterization of substation electromagnetic transients. Final report
Little quantitative data exists on radiated electromagnetic interference in substations arising from substation transients. The electromagnetic transient noise produced by normal substation activity such as opening switches and breakers can be significant. Additionally, abnormal events such as faults cause similar electromagnetic noise. The lack of data is in part because suitable measurement equipment techniques have not been generally available to utilities. A new approach to the measurement and characterization of electromagnetic interference caused by substation transients has been developed. A data acquisition system for measurements has been designed and constructed for field use with a bandwidth capability exceeding 100 MHz. Measurements have been taken from staged operations in substations and the resulting data analyzed using specialized computer programs developed for this project. The measurement techniques are presented and the analysis procedures explained in detail. The transients caused by equipment operations in several substations have been studied resulting in an understanding of the expected or typical amplitudes and frequencies of the resulting noise. Suggestions as to equipment tests and withstand levels have been made. An appendix includes raw and analyzed data for research use.
