Specification of Alternator:

Enclosure

  IP21-23(NEMA 1) is standard for all industrial and marine generators .

Shaft & Keys

 All alternator rotors are dynamically balance to better than Bs6861 P.1,G2.5 for minimum vibration in operation.Two bearing generators are balanced with a half-key. electric dynamo is used in diesel generator.

Terminal and terminal box

  The 3Phase alternators had 12 ends brought out to the terminal box .The terminals are put on the non drive end. The box is equipped with removable panels.

Voltage regulation

  Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%s fluctuation of the speed of engines .Voltage is adjusted using a trimmer on the AVR.

Telephone interference

  THF(as defined by BS4999 Part 40) is better than 2%. TIF(as defined by ASAC50.12) is better than 50.

Radio interference

    The absence of brush-gear and the high quality AVR ensure low levels of interference with radio transmissions. RFI suppression may be supplied if required .

Damper Winding

    The alternators incorporate a damper winding in order to ensure good parallel running with mains network and other machines. Inserted into the shoes of the poles are the bars of the damper winding which are connected together at each end of the poles to form a closed cage. This arrangement provides the alternator with excellent damping against the torsinal vibration that occurs during changes in load and when running in parallel.
