Capability of existing of ZnO lightning arresters with different dielectrics
The housing of zinc oxide lightning arresters are playing major role for discharging the lightning surges. Previously porcelain and silicon rubber housings were mainly used depending on the atmospheric conditions but in practice a lot of problems are faced with these housing. Hence this paper presenting the ZnO blocks performance characterizes with different dielectrics such as air, transformer...
متن کاملIntelligent Detection and Diagnosis of Lightning Arresters Faults Using Digital Thermovision Image Processing Techniques
This paper describes a methodology that aims to detect and diagnosis faults in lightning arresters, using the thermovision technique. Thermovision is a non-destructive technique used in diverse services of maintenance, having the advantage not to demand the disconnection of the equipment under inspection. It uses a set of neuro-fuzzy networks to achieve the lightning arresters fault classificat...
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 کاملPerformance of Surge Arrester to Multiple Lightning Strokes on Nearby Distribution Transformer
Overhead distribution lines are prone to lightning overvoltages due to their configurations and characteristics. Metal Oxide Varistor (MOVs) arresters for many years have proven to be more advantageous than others arresters in lightning surge protection; therefore it is worthwhile to continually assess the behavior and performance of these arresters to different kind of overvoltages caused by l...
متن کاملLightning Performance of High Voltage Transmission Lines Protected by Surge Arresters: a Simulation for the Hellenic Transmission Network
Lightning strikes to overhead transmission lines are a usual reason for unscheduled supply interruptions in the modern power systems. In an effort to maintain failure rates in a low level, providing high power quality and avoiding damages and disturbances, plenty of lightning performance estimation studies have been conducted and several design methodologies have been proposed. The protection o...
