What size generator should a power plant have?
Generators for a power plant serving an installation will be in the range from 4160 volts to 13.8 kV to suit the size of the unit and primary distribution system voltage. Generators in this size range will be offered by the manufacturer in accordance with its design, and it would be difficult and expensive to get a different voltage rating.
What is a terminal voltage rating for a power plant generator?
Terminal voltage ratings for power plant generators depend on the size of the generators and their application. Generally, the larger the generator, the higher is the voltage. Generators for a power plant serving an installation will be in the range from 4160 volts to 13.8 kV to suit the size of the unit and primary distribution system voltage.
