In electrical engineering, spikes are fast … 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 some voltage spikes may be created by current sources. Voltage would increase as necessary so that a constant current will flow. Current from a discharging inductor is one example. For sensitive electronics, excessive current can flow if this voltage spike exceeds a material's breakdown voltage, or if it causes avalanche breakdown. In semiconductor junctions, excessive electric current may destroy or severely weaken that device. An avalanche diode, transient voltage suppression diode, varistor, overvoltage crowbar, or a range of other overvoltage protective devices can divert (shunt) this transient current thereby minimizing voltage. Voltage spikes, also known as surges, may be created by a rapid buildup or decay of a magnetic field, which may induce energy into the associated circuit. However voltage spikes can also have more mundane causes such as a fault in a transformer or higher-voltage (primary circuit) power wires falling onto lower-voltage (secondary circuit) power wires as a result of accident or storm damage. Voltage spikes may be longitudinal (common) mode or metallic (normal or differential) mode. Some equipment damage from surges and spikes can be prevented by use of surge protection equipment. Each type of spike requires selective use of protective equipment. For example, a common mode voltage spike may not even be detected by a protector installed for normal mode transients. Power increases or decreases which last multiple cycles are called swells or sags, respectively. An uninterrupted voltage increase that lasts more than a minute is called an overvoltage. These are usually caused by malfunctions of the electric power distribution system.of the electric power distribution system.

* 闪电
* 停電
* 斷路器跳脫
* 短路
* 同一電源上其他大電力設備的暫態
* 電力公司的誤動作
* 電磁場能量產生的电磁脉冲（EMP），頻率範圍從100 kHz到1 MHz。
* 电感突波 在設計關鍵設備以及軍用硬體時，需要考慮核爆炸產生的脈波，核爆炸會在大氣中產生大能量的電磁脈波的能量很大，頻率從1 kHz到數 GHz 的等級。 電壓突波也會帶來電流的變化（電流突波）。不過也有可能因為電流源而產生電壓突波。因一電路的電流會維持定值，就可能因為阻抗突然變大而產生電壓突波。例如若有儲能的电感元件突然斷路，又沒有續流路徑，就會有突波。 針對對電壓敏感的電路設備，若電壓突波超過材料的擊穿電壓，或是造成突崩潰，會讓設備流進過多的電流。半导体PN结若流進過多的電流會使元件損壞或是減弱。針對電壓突波有許多的保護裝置，例如雪崩二極管、瞬态电压抑制二极管、壓敏電阻、過電壓或是其他的过电压保護裝置可以分散（）暫態電流，因此減小電壓。 電壓突波也稱為surges，也可能是因為磁場的快速建立或快速消退所造成（其电磁感应能量反映在電路上）。不過電壓突波也可能是因為其他常見的原因造成，例如因為意外或是風暴变压器或高壓電源線誤短路到低壓的電源線，也會有電壓突波。 電壓突波可能是共模的（common mode），也可能是差模（differential mode）。有些設備可以加裝电涌保护器，避免因為突波而破壞設備。每一種突波都需要選擇對應的保護設備。例如若保護器是裝在二條電源線之間，可以抑制差模的暫態，但無法抑制共模的電壓突波。 電功率增加或減少，且持續數週期，稱為swell或sag。若電壓上昇超過一分鐘，稱為過電壓。一般是因為配電系統異常所造成的。well或sag。若電壓上昇超過一分鐘，稱為過電壓。一般是因為配電系統異常所造成的。
