Elektrische, insbesondere aber elektronische Meß-, Steuer-, Regel- und Schaltkreise, vor allem auch Fernmeldeeinrichtungen und -anlagen, sind empfindlich gegen transiente Überspannungen, wie sie insbesondere durch atmosphärische Entladungen, also durch Blitzströme, aber auch durch Kurzschlüsse und Schalthandlungen in Energieversorgungsnetzen auftreten können. Diese Empfindlichkeit hat in dem Maße zugenommen, in dem elektronische Bauelemente, insbesondere Transistoren und Thyristoren verwendet werden; vor allem sind seit vielen Jahren zunehmend eingesetzte integrierte Schaltkreise in starkem Maße durch transiente Überspannungen gefährdet.Electrical, but in particular electronic measuring, control, regulating and switching circuits, especially telecommunications equipment and systems are sensitive to transients Surges such as those caused by atmospheric discharges by lightning currents, but also by short circuits and switching operations in energy supply networks may occur.
