Transienta overspanningar

hundra mikrosekunder. Pa grund av dess korta existens brukar de oftast kallas for transienta overspanningar eller transienter. De varsta transienter orsakas av blixtnedslag vid aska och medfor en mycket hog spanningstopp. Denna typ av transient brukar vara mycket hogre an sadana som. 1 2 This thesis offers a general understanding of Very Fast Transient Overvoltages (VFTO or VFT) and explores different mitigation techniques, mainly based on dissipation of the energy associated with it. Two solutions are mainly discussed for attenuating the VFTO: applying a semi resistive and magnetic coating or using magnetic rings. 3 4 Corpus ID: ; Asktransienter och overspanningar: En spanningsfylld simulering av elkraftsystemet vid Forsmark 3 @inproceedings{AhlstrmsktransienterO. 5 Many translation examples sorted by field of work of “transient overspanning” – Swedish-English dictionary and smart translation assistant. 6 A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment w. 7 8 Overspanningar uppstar pa brakdelen av en sekund. 9 Transienta overspanningar ar spanningsstotar som kan na tiotals kilovolt pa mikrosekunder. 10 11 12
