The on-line calibration of capacitive voltage dividers used in low impedance pulse forming lines is discussed, and a parallel inductance is proposed to compensate the capacitive load of the forming line. Due to the low impedance of the forming line, the calibrated waveform will lack flattop if a short pulse square wave generator is used, and the calibrated waveform will have poor signal noise ratio if low voltage sine wave generator is used. By using a parallel-connected inductance, a parallel resonance circuit is formed. Low distortion and high voltage can be obtained from the amplifier. The method can be used in on-line calibration of microsecond capacitive voltage dividers in forming line voltage measurement.
