PI144D Stamford Alternator
PI144D Alternator by Stamford
A major component of the Cummins C22D5 diesel generator, the PI144D Stamford three-phase alternator can produce a prime power output of 20kVA and standby power output of 22kVA when run at 50 Hz over a range of voltages from 380 to 440 volts. From the P0/P1 series by Stamford the PI144D is a mid-size alternator. The PI144D alternator has been manufactured in Wuxi, China since 2020. P1 alternators are mainly used for standby applications & small power output applications. The P1 alternators have the options of 2 and 4 pole, enabling it to be very versatile for more demanding and challenging applications.
When looking at the PI144D from the drive-end the alternator rotates clockwise. The PI144D Stamford alternator deploys a self-exciting excitation system with an AS480 AVR (The AVR is used for automatically maintaining generator output terminal voltage at a set value by sensing the voltage V out at a power-generating coil and comparing it to a stable reference.) control system with an excitation boost system (EBS) option.
In the PI144D's self-excited system the main stator deploys power via the AVR to the exciter stator.
