“…In contrast to lightning or operation overvoltage, HEMP has a fast-rising edge of nanoseconds, placing higher requirements on the protective performance of ZnO arresters [20][21]. Under different impulse waveforms, the response characteristics of ZnO arresters are also different, depending on the amplitude and rising rate of each impulse current.…”

Zinc oxide arresters, a major type of overvoltage protection equipment in power systems, can suppress transient lightning overvoltage, operation overvoltage, and other types of power surges. However, the response characteristics and protection effects under nanosecond pulses, such as those in a high-altitude electromagnetic pulse conduction region, remain unclear. Therefore, the surge protection performance of arresters should be properly understood, and high-performance arresters should be developed. In this study, critical parameters, including overshoot peak voltage, residual voltage, response time, and voltammetry characteristics of a representative 10 kV ZnO arrester under nanosecond pulses, were obtained using a double exponential pulse current injection source. The overshoot peak voltage of this arrester under a nanosecond pulse is 2.19 times of lightning impulse residual voltage, and the residual voltage ratio under a nanosecond pulse is 4.31. The average response time is approximately 45 ns, and the response time is independent of the nanosecond pulse amplitude. Furthermore, an electromagnetic transient model of this type of lightning arrester is established based on the CIGRE guidelines, as well as a method to determine the key parameters. The model can simultaneously account for the response characteristics of the small current region and the conduction region of the arrester, which properly agrees with the experimental results.INDEX TERMS ZnO arrester, response characteristics, nanosecond electromagnetic pulse, overvoltage protection, voltammetry characteristics.

“…However, this method only conducts relevant research on how to measure VFTO more accurately, without proposing corresponding countermeasures. The protective performance of metal oxide lightning arresters under nanosecond transient electromagnetic interference, including VFTO, was studied in [19]. Based on the 400 kV pulse generator test platform, experiments were conducted on the non-linear, fast pulse response, and transition impedance behavior of the protection performance.…”

The simulation models of the 500kV gas-insulated transmission lines (GIL) and gas-insulated substation (GIS) systems in a realistic nuclear plant are presented in the paper. The Very Fast Transient Overvoltage (VFTO) which is generated during switching operations, is analyzed. Some affecting factors on the level of the VFTO are investigated. These factors are the location of the power source, the entrance capacitance of the potential transformer (PT), and the capacitive voltage transformer (CVT). At last, some suggestions on overvoltage calculations or calculations of electromagnetic interference sources are proposed. The conclusions can be used in insulation designing and analyzing the electromagnetic interference on the secondary system in nuclear plants and substations.

“…The accurate placement and the determination of the electrical characteristics of the arresters organize critical issues that involve appropriate theoretical substantiation. This is reached by implementing simulation procedures, precision of which depends on the used equivalent circuit models (Bedoui and Bayadi, 2019; Jacqmaer et al , 2009; Li et al , 2021; Zhao and Magoulès, 2012; Zhou et al , 2020). Suitable equivalent models have been represented by many researchers to compute the SA residual voltage for fast-front current waves (Fernandez and Diaz, 2001; Pinceti and Giannettoni, 1999; Application of Surge Protective Devices Subcommittee, 2023).…”

Purpose This paper aims to focus on the inclusion of the frequency behavior of grounding system effect on surge arrester (SA) model parameters’ estimation. Design/methodology/approach The grounding system impedance and its frequency behavior are the factors that have influence on the SA performance. Up to now, the grounding system impedance effect and the frequency behavior of the soil parameters have not been studied for the estimation of the parameters of the SA frequency-dependent model. In this paper, the grounding system’s influence on the SA dynamic model has been simulated for rod- and counterpoise-shaped electrodes. Particle swarm optimization with a grey wolf optimization algorithm has been implemented as an optimization algorithm to adjust the parameters of the SA dynamic model. Findings The results show that the frequency behavior of the grounding impedance and soil electrical parameters can impress the optimum parameters of the SA frequency-dependent model and should be considered for more reliable results. Also, the results evidence that the proposed optimization method provides more accurate results compared to other optimization methods. Originality/value To the best of the authors’ knowledge, this work is one of the first attempts to investigate the effect of frequency grounding system on SA frequency-dependent model parameters.
