An undervoltage occurs when the electrical power supply drops below the normal voltage level, which can cause equipment to malfunction or stop working altogether. A blackout occurs when the power supply is completely cut off, resulting in a total loss of power. A power surge is a brief increase in voltage, and overvoltage occurs when the voltage exceeds the normal level for an extended period of time.
