3.6 Voltage dividing systems and impulse voltage measurements

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.

The problems arise with much higher voltages and it is well known that impulse voltages with magnitudes up to some megavolts ...
