IP23(NEMA 1) is standard for all industrial and marine generators .
Giving drip proof protection of 60° from the vertical.Inlet air filters are available as an option on all generators,at reduced rating (5% derate)
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.
Terminal and terminal box
Standard.generators are 3 phase reconnectable with 12 ends brought out to the terminals,which are mounted on a cover at the non-drive end of the generator. A sheet steel terminal box contains the AVR and provides ample space for customers’wiring and glad arrangments. It has removable panels for easy access.
Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 4%s fluctuation of the speed of engines .Voltage is adjusted using a trimmer on the AVR .
The insulation system is class ‘H’
.All wound components are impregnated with materials and processes designed specifically to provide protection against the harsh environments encountered in generator applications. Resin based materials are selected and developed to provide the high build required for static windings and the high mechanical strength required for rotating components.
Winding and electric features;
Generator stator is wound to 2/3 pitch. This eliminates triplen (3rd, 9th,15th…) harmonics on the voltage waveform and is found to be the optimum design for trouble-free supply of non-linear loads. The 2/3 pitch design avoids excessive neutral currents sometimes seen with higher winding pitches, when in parallel with mains. A full connected damper winding reduces oscillations during paralleling. This winding, with 2/3 pitch and carefully selected pole and tooth designs, ensures very low waveform distortion.
THF(as defined by BS4999 Part 40) is better than 2%. TIF(as defined by ASAC50.12) is better than 50.
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 .
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.
