Calibration of current and voltage probes in the electromagnetic-pulse transmission path and near the load of the Angara-5-1 facility

The metrological support of current and voltage measurements in the transmitting path and load of the Angara-5-1 facility is described. The techniques for calibrating probes are based on the excitation of pulsed current and voltage in the calibrated units of the facility. The levels of currents and voltages are 50-100 times lower than the operating values. Comparison of the signals from the calibrated probes to the signals of reference probes helps to determine the characteristics of the calibrated probes. Cross measurements were performed to verify the techniques.
