3.22 Voltage adjustment range. The minimum voltage adjustment range shall be:
Voltage Connection
Range
120/ 208 V
197 to 229 volts
240/ 416 V
395 to 458 volts
This voltage adjustment range shall apply for all load between no load and rated kW, rated
power factor at rated frequency under all environmental conditions. I t shall not be possible
to adjust the voltage of a value which activates the overvoltage protective device.
3.23 Endurance. The set shall operate for 3,000 hours without critical failure at all loads,
continuous and intermittent, up to and including rated load under all of the individual or
combination of conditions specified in 3.9.1 of the general specification.
3.24 Exciter field current. With the generator temperature stabilized at normal ambient
conditions, the exciter field current shall not exceed 1.78 amperes for rated load at 400 Hz
operation.
3.25 Generator efficiency. With the generator in the 120/ 208 V connection, the rated
load efficiency of the generator shall be equal to or greater than 86 percent.
