spänningsimpuls
Spänningsimpuls, often translated as voltage impulse or transient voltage, refers to a sudden, brief, and significant change in electrical voltage. These impulses are characterized by their rapid rise time and decay, deviating sharply from the normal operating voltage of an electrical system. They can be positive or negative in polarity and vary in duration, though they are typically of very short duration, often measured in microseconds or milliseconds.
Spänningsimpulser can originate from various sources. Natural phenomena such as lightning strikes are a primary cause,
The effects of spänningsimpulser on electrical and electronic equipment can be detrimental. They can exceed the
