The situation described involves a DC generator that has reached its maximum output while trying to overspeed an elevator during a safety test. When a generator is unable to increase its speed despite being required to do so, it indicates that the generator is responding to a condition where its ability to deliver additional power or lift is compromised due to its design limitations.

In this case, the generator is considered to be saturated. Saturation occurs when the magnetic core of the generator has reached its maximum magnetic flux density and can no longer respond to increasing current in a linear fashion. This saturation reduces the efficiency and capability of the generator to provide additional output, thereby limiting its performance despite any attempts to push it beyond its limits.

Recognizing that the generator is operating under these conditions is important for understanding both the limitations of the equipment and the necessary safety parameters during testing. The term ‘overloaded’ may imply that too much load is applied, but in this context, saturation specifically addresses the generator's inability to exceed physical electrical output, making it the more accurate characterization.
