Modern Electrical Diagnostics for Metal Oxide Surge Arresters
The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multip...
متن کاملModelling of Metal Oxide Surge Arresters in Simulation Software DYNAST
This paper describes the possibilities for mathematical modelling of gap-less surge arresters in the simulation software DYNAST. This tool does not belong to standard modelling softwares in the field of electric power engineering. However, it may provide some key advantages when compared to more frequently used software such as EMTP-ATP and MATLAB-Simulink. Description of the metal oxide varist...
متن کاملLeakage Current Analysis of Polymer and Porcelain Housed Metal Oxide Surge Arresters in Humid Ambient Conditions
This paper aims to measure and analyze of the leakage current of 20 kV polymer and porcelain metal oxide surge arresters under humid ambient conditions by applying different voltages to the arresters terminal. The characteristics of the leakage currents at that stage have been investigated when changes in the ambient humidity were introduced in an artificial fog chamber. It is assumed that magn...
متن کاملEvaluation of lightning performance of transmission lines protected by metal oxide surge arresters using artificial intelligence techniques
Lightning and switching overvoltages are the main causes for faults in electrical networks. In the last decades, several different conventional methodologies have been used for the adjustment of the lightning performance of high voltage transmission lines, which are protected against lightning using overhead ground wires and surge arresters. The current paper proposes a new developed Artificial...
متن کاملAdjusting the Parameters of Metal Oxide Gapless Surge Arresters’ Equivalent Circuits Using the Harmony Search Method
The appropriate circuit modeling of metal oxide gapless surge arresters is critical for insulation coordination studies. Metal oxide arresters present a dynamic behavior for fast front surges; namely, their residual voltage is dependent on the peak value, as well as the duration of the injected impulse current, and should therefore not only be represented by non-linear elements. The aim of the ...
