(5) Electrical character

1. Excitation system
The standard AVR are EA05A-3,EA04;SX440,SX460 or MAX321(optional AVR)
The main stator provides power for excitation of the exciter field via AVR. The high efficiency Semiconductor inside AVR will ensure the output voltage up to the rated max from the lower gradually
Output power of exciters rotor is input to that of mains through3-phase full wave rectifier. Two ends of the rectifier are connected with permanent magnetic steel. It can make generator starting smoothly in any occasions.
All the adjusting rate of stable voltage of the AVR≤±1%.SX440 has parallel connection, low frequency protection, exterior voltage adjustment and other function. MAX321 is for the permanent magnetic motors.

2. Voltage regulation:
Voltage regulation refers to the change of from no-load with power factor ranging from 0.8 to 1 and 4%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR

3. Insulation
Insulation class H All the regular components are made up with special materials, also immersed in lacquer by peculiar tech. Varnish and colophony materials are developed to strengthen the processing and machinery intensity of windings and revolving parts for protecting the generator work under corrosive environment.

4. Windings and electric features
all the generator stators adopt high magnetic conductibility energy cold rolling silicon steel plate to fold up, double winding, firmly structure, good insulating. Continuous damp windings abate surges. The poles and gears of the windings are carefully chosen and this helps to check the wave distortion of output voltage.

(6) Mechanic features

1. Frame
All industrial standard generator is IP22(NEMA1).Also IP23 is an option. But rated power will decrease 5%, marine standard generator is IP 23.air filter is an option, but rated power of the generator will decrease 5% while it is installed.

2. Axis and keyAll of the alternator rotors should pass balance test, whose vibration are lower than the minimum of BS6861.P.1,G2.5.Two bearing generator has a half-key testing balance.

3. Terminal and terminal boxThe three-field generator has leads brought out to the terminals in the terminals box. The terminals are put on the non drive end. The box is equipped with removable panels.
