Voltage spike
Short duration voltage transient in an electrical circuit
Voltage spike
In electrical engineering, spikes are fast, short-duration electrical transients in voltage (voltage spikes), current (current spikes), or transferred energy (energy spikes) in an electrical circuit. Fast, short duration electrical transients (overvoltages) in the electric potential of a circuit are typically caused by Lightning strikes Power outages Tripped circuit breakers Short circuits Power transitions in other large equipment on the same power line Malfunctions caused by the power company Electromagnetic pulses (EMP) with electromagnetic energy distributed typically up to the 100 kHz and 1 MHz frequency range. Inductive spikes In the design of critical infrastructure and military hardware, one concern is of pulses produced by nuclear explosions, whose nuclear electromagnetic pulses distribute large energies in frequencies from 1 kHz into the gigahertz range through the atmosphere. The effect of a voltage spike is to produce a corresponding increase in current (current spike). However...
