“…Concerning the immunity mechanism, some scholars have already researched how the electrical devices are disturbed [13,[15][16][17]. Richelli reported on an amplifier exhibiting both intrinsic robustness to interferences and presented the successful design of a CMOS operational amplifier (opamp) with enhanced immunity to EMI.…”

The electronic current transformer (ECT) acquisition card is widely used in smart grids with many advantages. However, with the continuous improvement of the power grid and localized intelligent electronic devices, the electromagnetic environment under the operating conditions of gas insulated switchgear (GIS) substations is becoming more complicated. The reliability and safety of the ECT acquisition card will be endangered due to the complicated electromagnetic environment. In order to solve these problems, this paper investigates the electromagnetic disturbed mechanism of the ECT acquisition card. The effects of different grounding methods on the electromagnetic interference of the ECT acquisition card were studied. A platform based on IEC 61000-4-4 was built, and the electromagnetic interference (EMI) of the ECT acquisition card with different grounding methods was measured. The results show that the lower grounding impedance of the ECT acquisition system increased the internal EMI. Further, the high frequency electrical fast transient/burst coupling mechanism was analyzed. The parasitic parameters of the acquisition card were extracted based on the critical circuit by using the finite element method. Then, the high-frequency EMI coupling model of the ECT acquisition card was established.

“…Moreover, a simulation program with integrated circuit emphasis (SPICE) model for predicting electromagnetic emissions from an antenna is studied in [6]. As for the electromagnetic couplings, EMPs can penetrate into electric systems through back-door couplings and front-door couplings, many models are established to predict those coupling phenomena such as transmission lines models [7][8][9][10][11], apertures models [12,13]a n d antennas models [14][15][16]. Though electromagnetic emissions and couplings can be predicted by commercial full-wave simulators accurately, the increasing complexity of an electronic system makes the simulation quite time-consuming.…”

In this study, SPICE models of a multi-antenna system for transmitting and receiving are proposed. The radiation fields at a given direction can be predicted by the transmitting SPICE model when the system is excited by a set of excitation sources. The receiving SPICE model can be used to calculate the coupling voltages on each antenna's load when the antenna system is illuminated by plane waves. The proposed modelling method for transmitting and receiving is a three-step approach. In the first step, the radiation properties of the system are characterized by a minimal number of linearly independent radiation fields. Then, the transmitting and receiving equivalent models are established based on the radiation properties of the system. Finally, the equivalent models are approximated by rational functions and converted to SPICE models. Once these models have been established, the characteristic properties of the excitation signals can be changed arbitrarily without re-establishing the models. Besides, both models can be incorporated with any terminations. The proposed SPICE models have been validated by a commercial full-wave simulator. The feature selective validation method is used to quantify the models' results. Experiments are also conducted to validate the models.
