What type of interruption occurs only as long as necessary for service restoration?

The type of interruption that occurs only as long as necessary for service restoration is a momentary interruption. This disruption is typically very brief and is designed to minimize the downtime for consumers while allowing for quick assessment and resolution of issues. Momentary interruptions can often be the result of automatic protection systems within the electrical network, which temporarily disconnects service to prevent further damage or danger. This allows for a swift return to normal operations, making it a common strategy employed in power distribution systems to enhance reliability.

Scheduled interruption refers to planned outages that are communicated to customers in advance and are typically longer in duration, as they allow for maintenance or upgrades. A temporary outage typically signifies an interruption that lasts longer than a momentary interruption but is still expected to be resolved within a short timeframe. In contrast, a prolonged interruption refers to outages that extend over an extended period, often necessitating more extensive repairs or remediation efforts.
