-The generator is designed to operate together with a reciprocating engine. The stator frame is constructed with a rigid welded steel structure. The stator core is built of thin electric steel sheet laminations. The rotor consists of a shaft and salient pole type main revolving field.
The generator achieves very high efficiency because of the exceptional thermal conductivity created by the tight fit between the coils and the stator core.
-Terminals: The six stator winding ends are brought to terminal boxes on the generator sides. Terminals for monitoring and auxiliary equipment have separate terminal boxes.
-Damper winding: The generator is provided with a damper winding for parallel operation with other generators and with a separate power grid, if so connected.
-Shaft and bearing: The generator is horizontally mounted and provided with two sleeve bearings. The generator rotor is designed to minimise the effect of torsion rotor oscillations due to system disturbances and rapid load changes.
-Excitation: The exciter is of the brushless type with a rotating armature/rectifier assembled on the same shaft as the main generator rotating armature. The exciter field is controlled by the automatic voltage regulator (AVR). The rectifiers are of the silicon diode type in a full wave bridge arrangement. The rotating armature and stationary field of the exciter are insulated with Class F materials.
-Cooling (air-cooled): The generator is air-cooled. A fan mounted on the generator shaft takes cooling air from the engine hall, through washable filters, and passes it through the generator.
-Automatic voltage regulator: The voltage regulator is a completely solid state type for control of generator voltage by means of controlling the exciter field. The regulator controls the generator exciter field as required to maintain a constant and stable generator output voltage. (The AVR is installed in the generating set control panel).
