Global Power industrial generators meet the requirements of BS EN 60034 and the relevant section of other international standards such as BS5000, VDE 0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.
Other standards and certifications can be considered on request.
SX460 AVR - STANDARD
With this self excited control system the main stator supplies power via the Automatic Voltage Regulator
(AVR) to the exciter stator.
The exciter rotor output is fed to the main rotor through a three phase full wave bridge rectifier.
This AVR also operates in a self-excited system. It combines all the features of the SX440 with, additionally, three-phase rms sensing for improved regulation and performance. Over voltage protection is provided via a separate circuit breaker. An engine relief load acceptance feature is built in as standard.
Shaft & Keys:
All generator rotors are dynamically balanced to better than BS6861:Part 1 Grade 2.5 for minimum vibration in operation. Two bearing generators are balanced with a half key.
