What duration is considered characteristic of a momentary interruption in electrical systems?

A momentary interruption in electrical systems is typically defined as a short-duration event where the power supply is disrupted for a brief period. The duration of 33-133 milliseconds falls within the commonly accepted time frame for what constitutes a momentary interruption. This duration is brief enough that many devices can recover from it without a complete shutdown, as they are designed to handle transient faults or short outages.

In contrast, durations that extend beyond this range, such as 1-5 seconds or 300-500 milliseconds, would likely be classified as temporary interruptions or outages, which have more significant operational impacts and might require more robust measures for recovery. Meanwhile, the 15-30 milliseconds option, while closer to the lower threshold, often pertains to transients rather than sustained interruptions. Therefore, the range of 33-133 milliseconds accurately represents the typical duration recognized for momentary interruptions in electrical systems.
