What is Voltage spike?
[[File:Voltage spike.png|thumb|Voltage spike]] A '''voltage spike''' is a sudden increase in [[voltage]] value over a short time in [[Electrical power|power systems]]. It can be caused by several factors, but mostly it is due to [[Fault (power engineering)|external or internal disturbance]]. A voltage spike might cause an increase in [[Electric current|current]], but the increase in voltage might have been caused by the current increase as well. [[Category:Electricity]] {{sci-stub}}
