The measurement of impulse voltages even of short duration presents no
difficulties, if the amplitudes are low or are in the kilovolt range only. The
tremendous developments during the last three decades related to the technique
of common CROs, digital scopes or transient recorders provide instruments
with very high bandwidth and the possibility to capture nearly every kind of
short-duration single phenomena. Although the usual input voltage range of
these instruments is low, h.v. probes or attenuators for voltages up to some
10 kV are commercially available.
