A Study of High Transient Voltage Unit Realization Uncertainty

The problem of the metrological provision of generators of high-voltage voltage pulses with subnanosecond front rise time has been solved, as well as pulsed voltage splitters used in power engineering, aviation, and aerospace industries. As a result of the completion of the State Primary Special Standard for units of the intensities of pulsed electrical and magnetic fields with pulse front rise times in the range 0.1–10.0 ns per GET 148-2013, a mode of implementing the reproduction of the unit of high transient electric voltage with a minimum pulse front rise time of 100 ps has been implemented. The uncertainties of reconstituting the unit of high transient electric voltage, obtained by numerical modeling with the Monte Carlo method, are evaluated, as well as in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM). Likewise, the error of reproduction of the unit according to GOST 8.381-2009, “GSI. Standards. Methods of Expression of Precision,” is evaluated.
