| Abstract: | This paper analyzes the characteristics of RSD switching current, and selects measurement method by means of air-core coil. After comparison between self-integrator and out-integrator, a further study about the impact of phase error is made. Basis on the out-integrating measurement, a phase error control method is proposed to measure the RSD switching current which has low frequency components and nanosecond rising time. Actual measurements prove that this method can meet the RSD switching current measurement requirements. |
