System coordination is designed to temporarily remove what type of faults?

System coordination focuses on managing protective devices in a power system to ensure that only the affected section of a circuit is disconnected during fault conditions, allowing the rest of the system to continue operating normally. This approach is particularly effective for temporary faults, which may be caused by issues such as lightning strikes, fallen branches, or other transient disturbances that do not cause lasting damage to the system.

By employing system coordination, the protective devices can be set to recognize and quickly respond to these temporary faults, isolating them before they cause additional issues. Once the disruptive cause is cleared, the system can return to normal operation. This method emphasizes reliability and operational efficiency, as it minimizes downtime and enhances the stability of the electric supply.

In contrast, permanent faults typically involve breakdowns that cause irreparable damage, requiring more extensive repairs or replacements. Short-circuit faults, while also needing to be addressed urgently, fall under the category of electrical failures rather than temporary disruptions. Trivial faults are not generally recognized as a category needing specialized coordination, as they do not typically affect system reliability. Thus, the focus on temporary faults aligns with the goal of system coordination to ensure quick restoration and continued operation.
