Time Domain Analysis of Current Transducer Responses Using Impulsive Signals

For the measurement of impulsive currents, which might occur in cases electromagnetic interference, for example currents generated by non-linear behavior electronic appliances, a wide-band large dynamic range current transducer is needed. The electrical response such determined using conventional techniques, that use frequency sweeps sinusoidal continuous wave signals. and/or time invariant systems superposition signals multiple frequencies not be equal to an current, representative actual measured signals, and therefore interest. In this letter transducers compared tests. Time domain parameters as rise peak amplitude are extracted, analyzed Fourier transform. experiments show test agreement with method provides good alternative method. A combination impulses could cover bandwidth, fast cost effective approach.
