A momentary power interruption is a decrease to 0 V lasting for more than 3 sec up to 1 min. True or False?

The correct answer is based on the definition of a momentary power interruption. A momentary power interruption is typically characterized as a brief drop in voltage, which lasts for a duration that is usually considered to be less than 3 seconds. The definition implies that dropping to 0 V for any significant time, especially for a duration greater than 3 seconds but up to 1 minute, would not qualify as a momentary interruption and instead would be classified differently, such as a sustained outage.

Understanding the standards for power interruptions is essential. In power quality terminology, classifications often specify distinct time frames for different types of interruptions. Therefore, if the interruption lasts beyond the established timeframe for momentary events, it no longer fits this category, making the statement false.
