Alternativa cajas de conexión están disponibles para los clientes que quieren encajar componentes adicionales en la caja de bornes. EJE Y CLAVES Todos los rotores de generadores están equilibrados dinámicamente para mejorar de BS6861: Parte 1, grado 2.5 para un mínimo de vibraciones en operación. Dos generadores de cojinete están equilibrados con media chaveta. AISLAMIENTO / impregnación El sistema de aislamiento es de clase "H". Todos los componentes de la herida están impregnados con materiales y procesos diseñados específicamente para proporcionar el alto espesor requerido para devanados estáticas y la mecánica de alta la fuerza necesaria para hacer girar los componentes. ASEGURAMIENTO DE LA CALIDAD Los generadores son fabricados con la producción procedimientos que tengan un nivel de aseguramiento de calidad BS EN ISO 9001. La regulación de tensión declarado no podrá ser mantenida en la presencia de cierto radio de las señales transmitidas. Cualquier cambio en la práctica se encuentran dentro de los límites de Criterios 'B' de la norma EN 61000-6-2:2001. En ningún momento el estado de equilibrio regulación de voltaje superior al 2%. DE TARIFAS Todos los valores tabulados en la página 6 están sujetos a la siguiente reducciones 5% cuando los filtros de entrada de aire están montados. 3% por cada 500 metros de altitud en la que el funcionamiento supera los 1000 metros sobre el nivel del mar. 3% por cada 5 ° C por lo que el ambiente operacional temperatura supera los 40 ° C. Nota: El requisito para operar en un ambiente superior a 60 ° C deben ser remitidos a la fábrica. 5% Para la rotación inversa (CW rotación estándar cuando se ve desde el LA) NB desarrollo continuo de nuestros productos nos da derecho para cambiar detalles de las especificaciones sin previo aviso, por lo tanto, no deben ser considerados como vinculantes.

These guidelines have been formulated to ensure proper application of generator drive engines in A.C. generator set in-stallations. STANDBY POWER RATING: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. Under no condition is an engine allowed to operate in parallel with the public utility at the Standby Power rating. This rating should be applied where reliable utility power is available. A Standby rated engine should be sized for a maximum of an 80% average load factor and 200 hours of operation per year. This includes less than 25 hours per year at the Standby Power rating. Standby ratings should never be applied except in true emergency power outages. Negotiated power outages contracted with a utility company are not considered an emer-gency. PRIME POWER RATING: Applicable for supplying electric power in lieu of commercially purchased power. Prime Power applications must be in the form of one of the following two categories:UNLIMITED TIME RUNNING PRIME POW-ER: Prime Power is available for an unlimited number of hours per year in a variable load application. Variable load should not exceed a 70% average of the Prime Power rating during any operating period of 250 hours. The total operating time at 100% Prime Power shall not exceed 500 hours per year. A 10% overload capability is available for a period of 1 hour within a 12-hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year.LIMITED TIME RUNNING PRIME POWER: Limited Time Prime Power is available for a limited number of hours in a non-variable load application. It is intended for use in situations where power outages are contracted, such as in utility power curtailment. Engines may be operated in parallel to the public utility up to 750 hours per year at power levels never to ex-ceed the Prime Power rating. The customer should be aware, however, that the life of any engine will be reduced by this constant high load operation. Any operation exceeding 750 hours per year at the Prime Power rating should use the Con-tinuous Power rating.CONTINUOUS POWER RATING: Applicable for supplying utility power at a constant 100% load for an unlimited number of hours per year. No overload capability is available for this rating.

PI144DSPECIFICATIONS & OPTIONS
STANDARDS
Stamford industrial generators meet the requirements ofBS EN 60034 and the relevant section of otherinternational standards such as BS5000, VDE 0530,NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.Other standards and certifications can be considered onrequest.
VOLTAGE REGULATOR
AS480 AVR fitted as STANDARD
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 AS480 will support limited accessories, RFIsuppession remote voltage trimmer and for the P1 rangeonly a 'droop' Current Transformer (CT) to permit paralleloperation with other ac generators.The AVR is can be fitted to either side of the generator inits own housing in the non-drive end bracket.
Excitation Boost System (EBS) (OPTIONAL)
The EBS is a single, self-contained unit, attached to thenon-drive end of the generator.The EBS unit consists of the Excitation Boost Controller(EBC) and an Excitation Boost Generator (EBG). Underfault conditions, or when the generator is subjected to alarge impact load such as a motor starting, the generatorvoltage will drop. The EBC senses the drop in voltageand engages the output power of the EBG. Thisadditional power feeds the generator’s excitation system,supporting the load until breaker discrimination canremove the fault or enable the generator to pick up amotor and drive the voltage recovery.
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 atthe non-drive end of the generator. Dedicated singlephase generators are also available. A sheet steelterminal box contains provides ample space for thecustomers' wiring and gland arrangements. Alternativeterminal boxes are available for customers who want to fitadditional components in the terminal box.
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 materials and processes designed specifically to provide the high buildrequired for static windings and the high mechanicalstrength required for rotating components.
QUALITY ASSURANCE
Generators are manufactured using productionprocedures having a quality assurance level to BS EN ISO9001.
The stated voltage regulation may not be maintained inthe presence of certain radio transmitted signals. Anychange in performance will fall within the limits of Criteria'B' of EN 61000-6-2:2001. At no time will the steady-statevoltage regulation exceed 2%.
DE RATES
All values tabulated on page 6 are subject to the followingreductions
5% when air inlet filters are fitted.3% for every 500 metres by which the operating altitudeexceeds 1000 metres above mean sea level.3% for every 5°C by which the operational ambienttemperature exceeds 40°C. Note: Requirement for operating in an ambient exceeding 60°C must be referred to the factory.
5% For reverse rotation(Standard rotation CW when viewed from DE)
