All „Supra“ with your grid?

Today’s devices and equipment such as switched-mode power supplies, frequency converters, controlled drives, charging devices for e-mobiles or LED lighting work internally with high clock frequencies in order to regulate power efficiently. These can lead to line-borne as well as field-borne (coupled) interference in the power grid. In this technical report, we explain how you can detect these sources of interference in the grid using suitable measurement technology.
