Angle determination of voltage and current harmonics in practice

Today’s devices and equipment such as switched-mode power supplies, frequency converters, regulated 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 both conducted and field-bound (coupled) influences in the energy grid. In this technical report, we explain how you can detect these sources of interference in the grid using suitable measuring technology.
