Simulation of Lightning Overvoltages in Electrical Power Systems
Lightning strikes to overhead transmission lines cause travelling waves which propagate along the overhead line and enter substations where they cause overvoltages which can pose a risk to any items of equipment connected, such as cables or transformers. With the use of metal-oxide arresters, these overvoltages are reduced to values which, taking into account an adequate safety margin, are belo...

15 صفحه اول: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولMitigation of Transient Overvoltages Generated Due to Switching Operations and Lightning in Gas-insulated Substation (GIS) Without Extra Limiter
Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...
متن کاملInsulation coordination of MV cables against lightning - induced overvoltages generated by LEMP - coupled overhead lines
-The paper deals with the stresses of cable insulations due to lightning induced overvoltages for the case of distribution networks composed by MV overhead lines and buried cables. We are here interested only in the conditional probability of the cable breakdown in absence of line flashovers, which means that flashovers along the overhead line are disregarded. We illustrate a procedure based on...
