What is the usual generation voltage range of a power plant?

The typical generation voltage range for power plants is crucial for understanding how electricity is produced and transmitted. The correct answer falls within the range of 13,200 volts to 25,000 volts, which is common for many generating stations, especially those that are part of regional transmission networks.

Power plants often generate electricity at voltages lower than those used for long-distance transmission, as it allows for the use of efficient transformer steps to increase the voltage for transmission over long distances. This method is essential to minimize energy losses as electricity travels through power lines.

Options outside this range generally represent different phases in the electrical supply chain. For instance, generation voltages that are too low may not be effective for distribution purposes, while much higher voltages, like 100,000 volts to 230,000 volts, are typically associated with transmission lines rather than the initial generation phase.

Understanding these voltage levels helps linemen to grasp the context of safe handling, equipment rating, and the overall electrical grid's operation.
