Alternator Stamford UCI224F, 4P, 3F, Brushless, AVR,1500/1800,50/60 Hz, 72,5/93,8 KVA, SAE 3/11,5"

STANDARDSNewage Stamford industrial generators meet the
requirements of BS EN 60034 and the relevant sectionof other international standards such as BS5000, VDE 0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.Other standards and certifications can be considered on request.
WINDINGS & ELECTRICAL PERFORMANCE
All generator stators are 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 the mains. A fully connected damper
winding reduces oscillations during paralleling. This
winding, with the 2/3 pitch and carefully selected pole
and tooth designs, ensures very low waveform
distortion.
TERMINALS & 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 the customers' wiring and gland
arrangements. It has removable panels for easy
access.
SHAFT & KEYS
All generator rotors are dynamically balanced to better
than BS6861:Part 1 Grade 2.5 for minimum vibration in
operation. Two bearing generators are balanced with a
half key.
INSULATION/IMPREGNATION
The insulation system is class 'H'.
All wound components are impregnated with materials
and processes designed specifically to provide the high
build required for static windings and the high
mechanical strength required for rotating components.
QUALITY ASSURANCE
Generators are manufactured using production
procedures having a quality assurance level to BS EN
ISO 9001.
The stated voltage regulation may not be maintained in
the presence of certain radio transmitted signals. Any
change in performance will fall within the limits of
Criteria 'B' of EN 61000-6-2:2001. At no time will the
steady-state voltage regulation exceed 2%
