The condition that refers to a reduced voltage level of AC power that lasts for an extended period of time is called a brownout.

Brownouts are characterized by a temporary drop in voltage in an electrical power supply system. They can occur due to increased demand on the electrical grid or issues with the supply. During a brownout, appliances and electrical devices may experience insufficient voltage to operate efficiently, which can lead to erratic performance or malfunction. Unlike sags, which are brief voltage drops, or surges, which are abrupt increases in voltage, a brownout is sustained and can last from minutes to hours, affecting overall power quality and reliability.
