Abstract:
An effect of integration circuit time constant on output voltage is conducted. When using external integration Rogowski coils to measure transient single pulse current. The cause of voltage waveform distort ion of integration circuit is given and the revision method of this kind of distort ion is offered. The revision method is fit for the measurement in which the integration circuit t ime constant of external integration Rogowski coil is not 10 times greater than the width of pulse current. This kind of correction greatly reduces the error in the measurement of pulse current and enlarges the application range of Rogowski coil.
