Manual for Operation V 5.24 44 / 80
7. Fast Damped Oscillatory 3 MHz, 10 MHz or 30 MHz as per IEC 61000-4-18
This phenomenon is representative of switching of isolators in HV / MV open-air stations, and is particularly
related to the switching of HV bus-bars, as well as of background disturbances in industrial plants.
