How many independent units does the power unit consist of?

• A. One, with no backup
• B. Two, one is online and the other in standby
• C. Three, for redundancy
• D. Four, for increased efficiency

Answer: (B)

The correct answer is based on the design of power units in many machinery systems, which often incorporate redundancy for operational reliability. The configuration of having two independent units—one actively operating while the other remains in standby—ensures that if one unit fails or requires maintenance, the second can take over without disruption to the system’s performance. This dual-unit setup enhances reliability and minimizes downtime. In various engineering applications such as ship machinery and power generation, the need for continuous operation is critical. Therefore, having one unit online and another on standby is a commonly adopted strategy to ensure availability and safety. This design mitigates risks associated with equipment failure, making it a sound choice in contexts where dependable operation is essential. Other configurations, such as three units for redundancy or four for efficiency, might exist in some advanced systems, but they are not as universally referenced for standard applications as the dual-unit approach.
