Electromagnetic noise emission measurements near the Flexible AC Transmission System (FACTS) device at the Sullivan (TVA) station

The expanded application of Flexible AC Transmission System (FACTS) technology to electric transmission and distribution systems frequently provides the best means of insuring the needed levels of capacity and reliability. This paper provides a review of electromagnetic emissions from a FACTS system tested at the Sullivan (TVA) Station. Electromagnetic interference (EMI) emissions from FACTS equipment may vary widely. Some of the data indicate potentially significant levels of emission, while data from other locations may be relatively benign. This variability highlights the need to be aware of the EMI issues when designing and applying FACTS devices to ensure that troublesome levels of emissions are avoided.
