What does the term "fault tolerance" refer to in electrical systems?

The term "fault tolerance" in electrical systems refers to the ability of a system to continue functioning properly even when one or more of its components fail. This is achieved through various design strategies that allow for redundancy, such as having backup circuits, multiple power sources, or failover mechanisms. By implementing these strategies, the overall system can maintain its operational integrity, minimizing downtime and avoiding total system failure.

In practical terms, fault tolerance is crucial in applications where reliability is paramount, such as in data centers, critical infrastructure, and safety systems. It ensures that the electrical system can endure failures without compromising its essential functions, thereby contributing to enhanced safety, reliability, and performance in electrical installations.
