The little A to Z of surge protectionSurge voltageA surge voltage is a voltage occurring briefly between conductors orbetween a conductor and the earth, which exceeds the highestpermissible operating voltage value by a long way, but does not havethe operating frequency. It can be created by storms or by earthing orshort-circuits.Temperature rangeThe operating temperature specifies within which temperature limits theperfect function of the surge protection device is guaranteed.Transient surge voltage (TOV)Temporary surge voltages are short-term (i.e. temporary) surgevoltages, which may occur due to errors within the medium and lowvoltagenetwork.Transmission frequency (fg)The transmission frequency specifies up to which frequency theinsertion damping of the employed resource is less than 3 dB.Volume resistance per path, series resistanceThe volume resistance per path specifies the ohmic resistance increaseof the conductor path per wire caused by the use of the surgeprotection device.Additional information02 TBS-Katalog_2010_Neuer_Stand / en / 30/03/2010 (LLExport_00986)114 OBO TBS
