Surge pulses occur due to direct or indirect lightning strokes to an external (outdoor) circuit. This leads to currents or electromagnetic fields causing high voltage or current transients. Another source for surge pulses are switching transients originating from switching disturbances and systems faults.
Due to the characteristic of the phenomenon nearly every electrical and electronical device may suffer from such lightning events which justifies the necessity of surge tests being widely performed. The EM Test VCS 500N8.5 8kV Combo Wave/Surge Generator offers a integrated coupling/decoupling network either single phase or three-phase with a nominal current of 16A per phase. In case higher current is required its capability can be extended by an external CDN to achieve nominal currents of 100A and more per phase.
