“…MWR(MOSA Wide-range) model(2017) proposed by Valdemir S. Brito was developed and validated based on MOSA electrical behavior in each one of the three operating regions of the zinc-oxide (ZnO) surge arresters, and in a database composed of voltage and current waveforms measured from tests performed in twelve ZnO varistors having different physical dimensions and electrical characteristicfrom five different manufacturers. It was shown that most of the waveform simulation results (under 8/20μs, 4/10μs and 3/6μs) were similar with the experimental data but the error was larger for the current impulse 1.5/26μs [14] . Some models were analyzed and studied by He Yuwei [15] and suggestion was put forward for reference.…”

“…Comply with GB 11032-2010 "Metal-oxide surge arresters without gaps for A.C. systems" during the test [17] , and MOVs (Table 1) were subjected to impulse currents with the following wave shapes: 8/20μs, 30/80μs and steep current with front time about 1μs. The residual voltage and energy absorption of MOVs under the corresponding impulse current were measured and recorded in Table III. The residual voltage values can be obtained easily, while energy absorption values in the test (Em) and simulation (Es) could be calculated using (14).…”

“…The MOA V-I characteristics can be divided into three regions to analyze [14] . In the region I, the current density is lower than 0.1mA/cm 2 , the V-I characteristic is approximately linear, and exhibits dependence on temperature, as well as capacitive behavior.…”

“…The accuracy of evaluating energy absorption is mainly affected by the waveform precision of impulse current and residual voltage. The current waveform difference between the simulation and the test at the end of the wave leads to the cumulative increase of the error in the calculation of the absorption energy (14). The reason that the error of the energy absorption is relatively large is that Heidler current source is used.…”

“…The simulation of the MOA model can be traced back to 1970s, since then, many models have been proposed [6][7][8][9][10][11][12][13][14] . The nonlinear inductance model [6] proposed by S. Tominaga(1979), can represent the dynamic characteristic for a narrow range of time to crest, where at least 20 voltage and current points as the conventional model are needed [7] .…”

The study on the simulation model of the metal oxide arrester (MOA) is of great significance to its production test and application. Simulation method is usually applied to MOA simulation test for some small and medium-sized enterprises with limited test conditions. The situation that there are a great wide variety of MOA models makes it more significant to study their applicability. The MOA simulation model research status was introduced in this paper, and three models, including IEEE model, Pinceti model and MWR model, were carried out by the Alternative Transient Program-Electromagnetic Transient Program (ATP-EMTP), where the Heidler current source and the RLC discharge circuit were used to produce different impulse currents, including 8/20μs, 30/80μs and steep current with front time about 1μs. Besides, the lightning impulse simulation of the whole arresters was experimentally researched under the nominal current. Then simulation results and experimental results were compared and analyzed according to the relative error of residual voltage and energy absorption. It is shown that the simulation waveform of the RLC discharge circuit is similar to the test waveform, which can effectively improve the problem of large relative error of the absorption energy, and the residual voltage simulation results of the three models are all good under 8/20μs and 30/80μs current. The IEEE model has shown good agreement in terms of the results of MOVs under steep current and the whole arresters under the nominal current. The difference between the two kinds of circuit design was analyzed, which can provide a reference for solving the problems in the current research, and improve work efficiency for testing institution.

Metal oxide surge arresters (MOSAs) have been widely used as protective devices against switching and lightning overvoltages in power electrical systems. MOSAs have dynamic characteristics in low‐ and high‐current regions. The unique model of MOSA, which is able to evaluate all the possible operating conditions of power systems, would surely be so complicated. Therefore, by the selection of an operating condition, the appropriate model of MOSA has been created. Many parameters affect MOSA performance in low‐ and high‐current regions. As a result, MOSA's performance under different operating conditions has been investigated by using a MATLAB GUI environment. To make a software environment to simulate MOSA performance in a high voltage laboratory, temperature variations influence on leakage current and its harmonic components under power frequency applied voltages and also the efficacy of impulse parameters variations on MOSA's residual voltage have been investigated. The designed graphical environment has been used by 40 electrical engineering students. The results showed that the use of the graphical environment had a great impact on the concepts' understanding of MOSA's performance.
