“…It can also be seen that, under power frequency voltage, with an increasing varistor temperature, the equivalent varistor resistance become smaller. Seyyedbarzegar [12][13][14][15] that the stray capacitance is independent of applied voltage and temperature. In this paper, finite element methods are used to calculate the stray capacitances in ANSOFT Maxwell software (V16 software, ANSYS company, Pittsburgh, PA, USA).…”

“…For an MOA, zinc oxide (ZnO) varistors are the core components, and the V-I characteristics of ZnO varistors show temperature dependence under power frequency-applied voltages [7][8][9][10][11]. What's more, when an AC voltage is applied to a MOA, the resistive current flowing through the ZnO varistors can cause power loss, which may lead to temperature rise or thermal failure of the MOA [12][13][14][15]. Thus, in order to improve the thermal stability of MOAs, it is of great significance to study the interaction of MOAs' temperature and power loss characteristics under power frequency overvoltages.…”

Metal-oxide arresters (MOAs) are used to absorb the electrical energy resulting from overvoltages in power systems. However, temperature rises caused by the absorbed energy can lead to the electrothermal failure of MOAs. Therefore, it is necessary to analyze the electric and thermal characteristics of MOAs. In this paper, in order to study the electric and thermal characteristics of MOAs under power frequency voltage, an improved electrothermal model of an MOA is presented. The proposed electrothermal model can be divided into an electric model and a thermal model. In the electric model, based on the conventional MOA electric circuit, the effect of temperature on the voltage-current (V-I) characteristics of an MOA has been obtained. Using temperature and applied voltage as input data, the current flows through the MOA can be calculated using the artificial neural network (ANN) method. In the thermal model, the thermal circuit of a MOA has been built. The varistor power loss obtained from the electric model is used as input data, and the temperature of the zinc oxide varistors can be calculated. Therefore, compared with the existing MOA models, the interaction of leakage current and temperature can be considered in the proposed model. Finally, experimental validations have been done, and the electrothermal characteristics of an MOA have been studied by simulation and experimental methods. The electrothermal model proposed in this paper can assist with the prediction of the electric and thermal characteristics of MOAs.

The voltage generated across a zinc-oxide (ZnO) element, in which a lightning impulse current flows, has been computed with the finite-difference time-domain (FDTD) method. Also, the distribution of temperature in the ZnO element has been computed on the basis of FDTD-computed conduction current densities with a discretized heat equation. The ZnO element having a thickness of 37 mm and a diameter of 34 mm is represented with many 1 mm × 1 mm × 1 mm cubic cells, each of which has a nonlinear resistivity in each of the x , y, and z directions dependent on the electric field in each direction and the temperature in each cell. Waveforms of voltage appearing across the ZnO element and the temperature on the side surface of the ZnO element computed for a short lightning impulse current having a magnitude of 66 kA agree reasonably well with the corresponding measured ones.

“…Zheng et al [10] studied the microstructure and electrical properties of the ZnO resistors at different annealing temperatures. Spackleigsnering et al [11] proposed a coupled electro quasi‐static‐thermal method for the simulation of surge arresters. Abdul‐Maleka et al [12] observed that the leakage current and temperature increase as a consequence of an increase in the applied voltage across the arrester.…”
