SPECIFICATIONS & OPTIONS
STANDARDS
WINTPOWER industrial generators meet therequirements of BS EN 60034 and the relevant sectionof other international standards such as BS5000, VDE0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.Other standards and certifications can be considered onrequest.





AUTO VOLTAGE REGULATORS
SX460 AVR – STANDARD
With this self excited control system the main statorsupplies power via the Automatic Voltage Regulator(AVR) to the exciter stator. The high efficiencysemiconductors of the AVR ensure positive build-upfrom initial low levels of residual voltage.The exciter rotor output is fed to the main rotor through athree phase full wave bridge rectifier. This rectifier isprotected by a surge suppressor against surges caused,for example, by short circuit.








AS440 AVR
With this self-excited system the main stator providespower via the AVR to the exciter stator. The highefficiency semi-conductors of the AVR ensure positivebuild-up from initial low levels of residual voltage.The exciter rotor output is fed to the main rotor through athree-phase full-wave bridge rectifier. The rectifier isprotected by a surge suppressor against surges caused,for example, by short circuit or out-of-phase paralleling.The AS440 will support a range of electronicaccessories, including a ‘droop’ Current Transformer(CT) to permit parallel operation with other acgenerators.











MX341 AVR
This sophisticated AVR is incorporated into the WINTPOWERPermanent Magnet Generator (PMG) control system.The PMG provides power via the AVR to the mainexciter, giving a source of constant excitation powerindependent of generator output. The main exciteroutput is then fed to the main rotor, through a full wavebridge, protected by a surge suppressor. The AVR hasin-built protection against sustained over-excitation,caused by internal or external faults. This de-excites themachine after a minimum of 5 seconds.An engine relief load acceptance feature can enable fullload to be applied to the generator in a single step.If three-phase sensing is required with the PMG systemthe MX321 AVR must be used.We recommend three-phase sensing for applicationswith greatly unbalanced or highly non-linear loads.













MX321 AVR
The most sophisticated of all our AVRs combines all thefeatures of the MX341 with, additionally, three-phaserms sensing, for improved regulation and performance.Over voltage protection is built-in and short circuitcurrent level adjustments is an optional facility.




WINDINGS & ELECTRICAL PERFORMANCE
All generator stators are wound to 2/3 pitch. Thiseliminates triplen (3rd, 9th, 15th …) harmonics on thevoltage waveform and is found to be the optimum designfor trouble-free supply of non-linear loads. The 2/3 pitchdesign avoids excessive neutral currents sometimesseen with higher winding pitches, when in parallel withthe mains. A fully connected damper winding reducesoscillations during paralleling. This winding, with the 2/3pitch and carefully selected pole and tooth designs,ensures very low waveform distortion.






TERMINALS & TERMINAL BOX
Standard generators are 3-phase reconnectable with 12ends brought out to the terminals, which are mounted ona cover at the non-drive end of the generator. A sheetsteel terminal box contains the AVR and provides amplespace for the customers’ wiring and glandarrangements. It has removable panels for easyaccess.





SHAFT & KEYS
All generator rotors are dynamically balanced to betterthan BS6861:Part 1 Grade 2.5 for minimum vibration inoperation. Two bearing generators are balanced with ahalf key.



INSULATION/IMPREGNATION
The insulation system is class ‘H’.All wound components are impregnated with materialsand processes designed specifically to provide the highbuild required for static windings and the highmechanical strength required for rotating components.



QUALITY ASSURANCE
Generators are manufactured using productionprocedures having a quality assurance level to BS ENISO 9001.


The stated voltage regulation may not be maintained inthe presence of certain radio transmitted signals. Anychange in performance will fall within the limits ofCriteria ‘B’ of EN 61000-6-2:2001. At no time will thesteady-state voltage regulation exceed 2%.
