The untimed current protection, also known as current quick-break protection, is designed to respond rapidly to short-circuit conditions. This type of protection is set based on the maximum short-circuit current that would flow through the protected component when an external fault occurs. Its main purpose is to ensure selective operation, allowing only the affected part of the system to be disconnected without disrupting the rest of the network. This feature is crucial in maintaining system stability and minimizing downtime during electrical faults. Additionally, it helps protect sensitive equipment from damage caused by excessive current. Proper configuration and coordination with other protective devices are essential for optimal performance.
