“…leakage current in the surge arrester under different temperatures at 10 kV applied voltage. From this table, it is noticed that the leakage current increases with the temperature of the arrester (Cheng et al, 2016;Lee et al, 2010;Seyyedbarzegar and Mirzaie, 2016;Seyyedbarzegar and Mirzaie, 2015;Späck-Leigsnering et al, 2016). The average error between the measurement and Leakage current reduction simulation results from the FEA model is 4.78 per cent, which is considerably small.…”

Purpose Leakage current is one of the factors, which can contribute towards degradation of surge arresters. Thus, the purpose of this paper is to study on leakage current within surge arresters and improvement on their design. Design/methodology/approach In this work, a three-dimensional model geometry of 11 kV zinc oxide surge arrester was designed in finite element analysis and was applied to calculate the leakage current under normal operating condition and being verified with measurement results. The optimisation methods were used to improve the arrester design by minimising the leakage current across the arrester using imperialist competitive algorithm (ICA) and gravitational search algorithm (GSA). Findings The arrester design in reducing leakage current was successfully optimised by varying the glass permittivity, silicone rubber permittivity and the width of the ground terminal of the surge arrester. It was found that the surge arrester design obtained using ICA has lower leakage current than GSA and the original design of the surge arrester. Practical implications The comparison between measurement and simulation enables factors that affect the mechanism of leakage current in surge arresters to be identified and provides the ideal design of arrester. Originality/value Surge arrester design was optimised by ICA and GSA, which has never been applied in past works in designing surge arrester with minimum leakage current.

“…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.

“…Hence, this is one of this method's disadvantages [25]. In addition, this method has some advantages, such as being a good indicator for the MOSA's condition evaluation and giving a realistic picture of MOSA's electrical characteristics and changes brought on by various types of degradation [60,61]. As a result, although it is insensitive to the operating voltage harmonics, even under direct or non-sinusoidal voltage, it provides reliable results and is another benefit of the power loss method [20].…”

Metal oxide surge arresters (MOSAs) are a popular solution for dealing with overvoltages due to lightning and switching in power distribution networks. As a result, a MOSA’s performance and longevity have a significant impact on the quality of energy and the frequency of outages. A MOSA performance is determined by several elements such as leakage current, partial discharge, and thermal image measured in various ways. In this study, different techniques for diagnostic and condition monitoring of MOSAs are discussed, and each method’s advantages and disadvantages are investigated. Additionally, the results of practical tests on two 20 kV healthy and degraded MOSAs are investigated and compared.
