Critical Clearing Time (CCT) is the maximum time duration that a power system can withstand a fault before it becomes unstable. It is crucial for ensuring system reliability and preventing cascading failures by allowing sufficient time for protective devices to isolate the fault.

A power system is an interconnected network designed to generate, transmit, and distribute electricity efficiently and reliably to consumers. It encompasses various components such as power plants, transmission lines, substations, and distribution networks, working synergistically to ensure a stable electricity supply despite varying demand and external factors.

System reliability refers to the probability that a system will perform its intended function without failure over a specified period under stated conditions. It is a critical factor in ensuring the dependability and efficiency of systems across various industries, impacting both performance and safety.

Cascading failures refer to a process where a failure in one part of a system triggers a chain reaction of subsequent failures, potentially leading to a large-scale system collapse. This phenomenon is particularly critical in interconnected and interdependent systems, where the failure of a single component can have far-reaching consequences across the entire network.

Protective devices are essential components in electrical systems designed to prevent damage from overcurrent, short circuits, and other electrical faults. They ensure the safety and reliability of electrical installations by interrupting the flow of electricity when abnormalities are detected.
