What transient torque percentage may occur, and for how long?

The transient torque percentage that can occur during certain operational conditions is critical for ensuring both the performance and safety of the system. When analyzing the correct choice, the specified range of 101% to 107% of the nominal torque for a duration of 5 seconds indicates acceptable limits for transient conditions.

This range allows for a slight increase in torque above normal operational levels without compromising the integrity of the system or its components. The 5-second duration limits the impact of this excess torque, allowing for brief interventions during startup, load changes, or fault conditions.

The choice succinctly captures acceptable operational tolerances, balancing the need for performance with the need for system reliability and safety. This short duration means there is minimal risk of overheating or undue stress that longer durations might cause, reinforcing the practicality of the operational range in real-world applications.

Other ranges presented in the other choices either exceed typical industry standards for transient conditions or prolong the duration, increasing the risk of potential damage or inefficiencies. Therefore, the selected range in the appropriate answer ensures that safety and operational efficiency are maintained under transient conditions.
