Suchvoltagesurgescancausedamagetosensorsandsignalcondi-

rierrailaccordingtoEN50022/EN50035intheswitchingcabinetor
inametalorplastichousingclosetothesensor.
Dependingontheversion,dierentcombinationsofprotectiveele-
mentsforvoltagelimitationareused.Typicalprotectiveelements
aresuppressordiodes(diodeswithspecialcharacterstics),varistors
(voltage-dependentresistors)aswellasovervoltagearresters(gas
arresters).
Assoonasthevoltageincreasestotheresponsevoltageofthe
protectiveelement,theelementbecomesconductiveandtheenergy
isdischargedtoground.Aftertheovervoltagehassubsided,the
