Abstract
The present disclosure discloses a voltage source for calibrating a very fast transient voltage measurement system, comprising a DC high voltage power supply, a discharging gap, a high voltage travelling wave line concluding a high voltage conductor and an earthing conductor. 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 is connected with the earthing conductor via the discharging gap, applying a high voltage between the high voltage conductor and earthing conductor and making breakdown of the discharging gap, 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.
