This essay derives and measures the current transfer functions of the air gaps of the core, analyzes the am- plitude-frequency and phase-frequency characteristics of the current transformer in different air-gap width condi- tions, and gives corresponding step response characteristics in such conditions. The essay proves that reasonable air gaps in the design, manufacturing and application of the current transformer can increase the measurement accuracy of the open-type current transformer.
