In medium voltage distribution network covered conductors are used to improve reliability and reduce interruptions and faults caused by snow, ice, storm and fallen trees; however covered conductors are more vulnerable than bare conductors against lightning caused burndown, therefore arc protection devices should be used. To study covered conductor overhead lines in case of direct lightning strike...
In a stage of development of the project and during the exploitation of transmission line (TL), the specialists have to solve one of the most complicated problems — insulation failures llashover rate (IFFR). The main indicator of the IFFR of TL is the minimization of the probability of outages, which is irreversible destructions of the isolating TL designs. When using valid normative documents, for...
Lightning protection system is an effective way to properly protect structures against hazardous effects of lightning strike. Lightning protection zone is an essential parameter of lightning protection system, because it determines whether structure is protected against lightning strikes. The rolling sphere method is commonly used to estimate lightning protection zone, but it neglects some significant...
