Electrical Character


EXCITATION SYSTEM SX440(460)
The main stator provides power for excitation of excitor field by Automatic voltage regulator. The efficient semi- conductors of Automatic voltage regulator ensure that the output voltage grows gradually from lower residual voltage to rated voltage. Over excitation voltage protection is prevented continually over voltage caused by alternator faulty.
The standard sensor is 2 phase sensing and supply the stable voltage regulation rate. The output power of excitor rotor is supported to the main stator through 3-phase full wave rectifier. The rectifier has surge resistance and avoids the impact caused by short circuit or parallel synchronzation loss.

VOLTAGE REGULATION RATE
The voltage regulation refers to the change of voltage from no-load to full load (including from cold to hot state) with power factor changing from 0.8 to 1 and 4% fluctuation of engine speed, It can be adjusted by adjustmeter on the Automatic voltage regulator.Voltage regulation rate is ±1%.
