“…The voltage-current characteristic of the SPD can be obtained by using the residual voltage, VR, at the peak of the current, IR, in order to avoid inductive effects on voltage measurement [34] since the current derivative, dI/dt, is practically zero at tR (Fig. 7b).…”

“…L can be evaluated based on (3) since all the other parameters are known through experimental records. Equivalent inductance is associated with the intrinsic inductance of the conductive paths within the structure of the SPD [34], the inductive-like behavior of protective components, and it is contaminated by the mutual inductance of the measuring circuit [31]; the latter can be practically eliminated by employing a voltage measurement setup as shown in Fig. 3.…”

This work introduces an experimental methodology for time-domain modeling of low-voltage surge protective devices (SPDs), accounting for their sparkover performance as well as their resistive, inductive, and capacitive behavior. The modeling procedure is demonstrated through an application to a combination type SPD connected to the DC side of electric vehicle charging stations. An equivalent circuit model is developed based on experimental records acquired from applied voltages and currents of a wide frequency range and energy content. The developed lumped-circuit model yields results in very good agreement with experimental data regarding sparkover voltage, residual voltage, and energy absorption of SPDs, as illustrated through ATP-EMTP simulations. The proposed methodology can be an effective tool for surge protection and insulation coordination studies.

“…As power systems continue to advance, the frequency of failures in power metering equipment is on the rise. This poses a major risk to the seamless functioning of power systems [2]. Therefore, it becomes more and more important to diagnose the black box fault of electric power metering device, which reduces the workload of manual diagnosis and increases the efficiency of fault diagnosis.…”

The knowledge base of black box fault diagnosis of electric power metering device contains a large number of abnormal features, which leads to unsatisfactory fault diagnosis results. Therefore, a black box fault diagnosis method of electric power metering device based on digital filtering and EMD method is proposed. Filtering the black box information of the power metering device under the digital filter; According to EMD method, a knowledge base is established for the black box fault diagnosis of power metering devices, and the local information increment matrix based on local sampling data information is used to judge whether there is a fault, thus completing the black box fault diagnosis of power metering device. According to the experimental findings, the proposed fault diagnosis method exhibits a negligible distinction and the calculated theoretical catastrophe value, the diagnosis result is the most accurate and consistent with the actual value, and the abnormal value of the diagnosis is 0, which has a good diagnosis effect.

“…Switching type devices with considerable extinguishing capabilities are also available in the surge protection industry [5][6][7]. However, one key advantage is that switching type components provide a low I 2 t stress to the equipment under protection [8]. GFSA operates on the principle of gas electrical breakdown.…”

Study of Breakdown Voltage Stability of Gas-Filled Surge Arresters in the Presence of Gamma Radiation

The results presented in this article relate to the study of the impact of gamma radiation on the breakdown voltage of gas-filled surge arrester manufactured by CITEL, Littelfuse and EPCOS at an operating voltage of 230 V. Radium was considered as a source of gamma radiation in this research. The stability of breakdown voltage as well as the reliability of gas-filled surge arresters of different manufacturers were investigated using different statistical methods. This gas component operation was based on processes that lead to electrical breakdown and discharge in gas. The breakdown voltage has a stochastic nature, and it is a subject of certain distribution. One thousand voltage measurements of breakdown voltage were carried out for each value of the voltage increase rate, from 1 V/s up to 10 V/s, with and without the presence of additional gamma radiation. The detailed statistical analysis of the obtained experimental data was performed for both cases for all three GFSA types. Moreover, the cumulative distribution functions of breakdown voltage were presented with the applied Weibull distribution fit. The coefficient of correlation as well as Pearson χ2 test showed the strength of the relationship between the experimental distribution functions and the Weibull distribution fits. The values of the Weibull distribution coefficients for all voltage increase rates and for all components were also analyzed with and without gamma radiation.
