✍️ Sample CMRT Questions & Answers
1. A technician is completing corrective maintenance on a 480V motor control center bucket. Before closing the compartment door and re-energizing, the FINAL verification step should be:
Foreign material intrusion (tools, hardware, wire scraps) inside energized switchgear is a leading cause of arc flash events and equipment damage.
2. What is 'over-greasing' a bearing and why is it harmful?
Over-greasing packs the bearing housing with excess grease, causing the rolling elements to churn the lubricant, generating heat, and ultimately leading to premature bearing failure.
3. Ferrography (analytical ferrography) in oil analysis provides information that routine spectroscopy does NOT, specifically by:
Analytical ferrography separates and deposits wear particles on a substrate for microscopic examination, revealing particle shape, size, and surface features that identify the wear mechanism.
4. What is a key concept in equipment reliability?
A key concept in fostering equipment reliability is the systematic execution of routine checks and the ability to detect issues early. Through consistent inspections and condition monitoring, potential problems can be identified and addressed in their initial stages. This proactive maintenance strategy is fundamental to minimizing unexpected downtime, optimizing asset performance, and reducing overall operational costs.
5. When establishing PdM inspection route frequencies, the primary factor that should drive how often a machine is monitored is:
The P-F interval defines the detection window available; inspection frequency must be set at no more than half the P-F interval to reliably catch faults before functional failure.
6. Which measure describes the probability that a failed system will be restored to operating condition within a specified time?
Maintainability is the probability that a failed item will be restored to a specified condition within a given time when maintenance is performed.
