Which meter readings indicate motorization of a generator?

The correct answer highlights a scenario where the kW meter reads zero or lower, the ammeter shows a current, and the power factor is moving off scale. This indicates that the generator is being motorized, meaning it is operating in a way that it is consuming more reactive power than it is producing, effectively causing it to draw current while delivering no real power.

When the kW meter indicates zero or negative readings, it suggests that the generator is not delivering power to the grid and might be operating as a motor instead. The presence of amperage indicates that there is still current flowing, which is necessary for motorization. The situation where the power factor is moving off scale indicates that the reactive power flow is becoming unstable, reinforcing the idea that the generator is now functioning like a motor rather than a power generator.

In contrast, other choices reflect conditions contrary to motorization, such as the presence of maximum power output or stable power factors which indicate normal operational conditions for a generating unit. The fluctuations or high stable readings on kW meters would showcase scenarios synonymous with typical generator operations, which do not align with the characteristics of a generator being motored.
