Electrical Fast Transients
(EFT) are interference pulses that can affect electronic circuits. Like
theLightning Electromagnetic Pulse (LEMP), the EFT pulse is triggered by a switching operation and occurs as a pulse packet (burst
). It istriggered by the bouncing
ofrelays or the switching of mechanical switches
and is located in the kilohertz range in terms of frequency. The interference induced in analog and digital circuits can trigger malfunctions in them.
