过电压指的是电路中一处或多处的电压超出了其设计的最高值。按照持续时间不同，可以分为短时的脉冲和长时间的浪涌。
电力和电子设备一般都被设计成在一个特定的电压下工作。如果提供的电压超出设计的极限，轻则可能会损坏设备，重则会导致设备起火、爆炸。

Overvoltage 过电压
When the voltage in a circuit or part of it is raised above its upper design limit, this is known as overvoltage. The conditions may be hazardous. Depending on its duration, the overvoltage event can be transient—a voltage spike—or permanent, leading to a power surge.
