Characterisation and Generation of High Impulse Voltages and Currents,restors, insulators, power cables, transformers, etc. They are exposed to high transient voltages and currents due to internal and external overvoltages. Before commissioning, they are therefore tested for reliability with standard impulse voltages or currents. Depending on the apparatus and its pro

Representation of Impulses in Time and Frequency Domain,esentation are equivalent to each other, but which representation will be preferred in an individual case depends on the measurement task and the desired goal. In principle, specifications for the correct measurement of a signal can be derived from the waveform in the time domain as well as from the

Digital Recorder, Impulse Voltmeter and Impulse Calibrator,Other designations for such instruments are digital oscilloscope, transient recorder and digitiser, with which even certain constructional and functional principles are associated. Analogue impulse oscilloscopes, wherever necessary with storage screens or photographic recording, find only rarely app

Evaluation of Uncertainties of Measurement,approximate value which is designated as the estimate (of the value). The imperfection or, positively considered, the quality of a measurement is quantitatively expressed by a numerical value, i.e. the uncertainty (of measurement). The comparability of measurements done at different locations or at
