What distinguishes corrective maintenance from preventive maintenance?

• A. Corrective maintenance requires more manpower
• B. Corrective maintenance addresses issues after failure, while preventive maintenance seeks to avert failures
• C. Preventive maintenance is always more cost-effective
• D. There is no difference between the two types

Answer: (B)

The distinction between corrective maintenance and preventive maintenance lies primarily in their objectives and timing in relation to equipment failures. Corrective maintenance is performed after a failure has occurred; it aims to restore the equipment to operational condition once a problem has been detected. This type of maintenance is reactive, responding to unplanned events and addressing issues only after they necessitate attention. On the other hand, preventive maintenance is proactive. It involves regular, scheduled activities designed to maintain equipment, reduce the likelihood of unforeseen failures, and extend the overall life of equipment. By performing preventive maintenance, potential failures are identified and addressed before they can disrupt operations. Understanding this difference is crucial in maintenance planning and strategy, as it affects resource allocation, cost management, and overall reliability of systems within a substation or similar environments.
