Fault detection rate

Definition

Fault detection rate refers to the effectiveness of a system in identifying and locating faults within a power grid. A high fault detection rate indicates that the system can quickly and accurately detect issues, which is crucial for maintaining the reliability and efficiency of electricity distribution. This concept is closely tied to the methodologies used for fault location and isolation, as timely detection allows for faster response and remediation.
