Under-Voltage Threshold: Definition, Importance & Protection

Under-voltage threshold refers to the voltage level at which a system triggers a protective mechanism when the voltage falls below a certain point. In power systems, voltage drops can lead to equipment malfunctions or performance degradation. To prevent these issues, a threshold is set to monitor the voltage and ensure it remains within a safe range. When the voltage dips below the established threshold, the system activates protective measures to avoid equipment damage or failures.
