Ferroresonance often inflicts severe damage on electrical equipment like potential transformers (PTs), surge arresters, and circuit breakers. In this paper, a new passive (P) technique using Cex (external parallel capacitor) is proposed and its performance is compared with the methods using Rex (pa...
Metal Oxide Surge ArresterFrequency-Dependent ModelLightning and OvervoltageThis paper describes simplified modeling of metal oxide surge arrester (MOSA) to operate analysis. This model is a new model proposed (P-K Model) to verify the accuracy in order to compare with IEEE and Pinceti Model. ...
metal oxide surge arresterThis paper proposes an adaptive model for electro-thermal analysis of metal oxide surge arresters based on finite element method. The input of the proposed model has been derived from power loss curve using adaptive network based fuzzy inference system (ANFIS). Moreover, ...
Also, real voltage and leakage current signals, which have been measured experimentally from a 20 kV metal-oxide surge arrester, have been compared with simulation results. Results show that the proposed model can simulate the performance of metal-oxide surge arresters more accurately than the ...
Metal Oxide Varistors (MOVs) are important components to construct arresters which suppress overvoltage and divert surge in the power system. By building the numerical model of the microstructure of MOVs, their characteristics can be better studied and interpreted. Due to different production processes...
Lightning surge arresters serve as the current grid protection against fast transients but are designed and modeled for protection against lightning and switching transients. Surge arrester response to faster transients is not well known. This work defines a scalable metal-oxide surge arrester model ...
Metal oxide surge arresters are important equipments that apply to power system for protection against switching and lightning over-voltages. Surge arrester monitoring technique based on leakage current analysis is a conventional monitoring method. Lack of proper features and thresholds is most important ...
Thus, this paper describes aspects of modeling and simulating the performance of a protection system using metal-oxide surge arresters, when exposed to direct lightning. A practical methodology is developed for the specification, simulation and definition of the best sizing, location and number of ...
