What is relationship among generator voltage range and frequency, pole, speed?

日期: 2019-04-30
作者:

In most cases, generator is used as standby or emergency power, or parallel operation with power network. So generator voltage, frequency, and phase depend on network requirements in different countries. In the condition of without power network, generator is used as main power and its voltage and frequency depends on its load, or choose generator according to load, or choose load’s voltage, frequency according to generator’s output voltage and frequency .

Generator’s frequency is 50Hz or 60Hz generally.

The generator is three phases generally and single phase can be customized.  

Generator voltage is divided into low voltage and high voltage. Voltage class under 1000V is low voltage, and voltage class above 1000V is high voltage.

The relationship among frequency, speed and pole.
Among: F indicates frequency, N indicates speed, P indicates generator poles.
