AMETEK CTS OCS 500 N6 series
Manual for Operation V 5.24 67 / 80
10.4.3. Verification Parameter fast damped oscillatory wave
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.
