What is the range of transient voltages?

Transient voltages are short-duration voltage spikes that can occur in electrical systems due to various events like switching actions, lightning strikes, or sudden changes in load. The magnitude of these transient voltages can vary significantly, typically ranging from a few volts to several thousand volts.

Selecting the range of a few volts to several thousand volts is appropriate because it encompasses the common scenarios in electrical systems where transient events are observed. For instance, in residential, commercial, and industrial environments, transients can peak up to several thousand volts, especially in the context of induced lightning surges or capacitive switching.

Recognizing this range is critical for designing protective measures, such as surge protection devices and ensuring that equipment can withstand these voltage spikes, thereby preventing damage or failure. This understanding is essential in electrical measurement safety practices as it helps in anticipating and mitigating risks associated with transient events.
