摘要： The present disclosure discloses a voltage source for calibrating a fast transient voltage measurement system, comprising a DC high voltage power supply, a discharging gap, a high voltage conductor and an earthing conductor, wherein the high voltage conductor and the earthing conductor are high voltage insulated from each other and form a traveling wave line with constant wave impedance; the DC high voltage power supply is connected between the ends of the high voltage conductor and the earthing conductor; the discharging gap is connected between ends of the high voltage conductor and the earthing conductor; the discharging gap is broken down when the charging voltage on the high voltage conductor is risen to a certain amplitude. The present disclosure also provides a method for calibrating a fast transient voltage measurement system: the high voltage conductor is insulated from the earthing conductor, and is open circuit at one end and at the other end connected with the earthing conductor via the discharging gap, the high voltage breaks down the discharging gap, applying a high voltage between the high voltage conductor and the earthing conductor, a very fast transient high voltage is produced on the high voltage conductor and its waveform can be determined by theoretical calculation, the very fast transient high voltage with known waveform is used as the calibration voltage for calibrating the measurement system. This reaches the purpose of simplifying the structure of voltage source for calibrating the fast transient voltage measurement system as well as the calibration method.
