Product Description

Brushless Alternator 100kVA 100% Copper Wires 50Hz 400V For Diesel Engine

SPECIFICATIONS & OPTIONS

STANDARDS OF 100KVA BRUSHLESS ALTERNATOR
1. Stamford industrial generators meet the requirements of BS EN 60034 and the relevant section of other international standards such as BS5000, VDE 0530, NEMA MG1-32, IEC34, CSA C22.2-100, AS1359.
2. Other standards and certifications can be considered on request.

 

VOLTAGE REGULATORS SX460 AVR - STANDARD
1. With this self excited control system the main stator supplies power via the Automatic Voltage Regulator (AVR) to the exciter stator. The high efficiency semiconductors of the AVR ensure positive build-up from initial low levels of residual voltage.
2. The exciter rotor output is fed to the main rotor through a three phase full wave bridge rectifier. This rectifier is protected by a surge suppressor against surges caused, for example, by short circuit.

 

AS440 AVR FOR BRUSHLESS ALTERNATOR
1. With this self-excited system the main stator provides power via the AVR to the exciter stator. The high efficiency semi- conductors of the AVR ensure positive build-up from initial low levels of residual voltage.
2. The exciter rotor output is fed to the main rotor through a three- phase full-wave bridge rectifier. The rectifier is protected by a surge suppressor against surges caused, for example, by short circuit or out-of-phase paralleling.
3. The AS440 will support a range of electronic accessories, including a 'droop' Current Transformer (CT) to permit parallel operation with other ac generators.

 

MX341 AVR FOR BRUSHLESS ALTERNATOR
1. This sophisticated AVR is incorporated into the Stamford Permanent Magnet Generator (PMG) control system.
2. The PMG provides power via the AVR to the main exciter, giving a source of constant excitation power independent of generator output. The main exciter output is then fed to the main rotor, through a full wave bridge, protected by a surge suppressor. The AVR has in-built protection against sustained over-excitation, caused by internal or external faults. This de- excites the machine after a minimum of 5 seconds.
3. An engine relief load acceptance feature can enable full load to be applied to the generator in a single step.
4. If three-phase sensing is required with the PMG system the MX321 AVR must be used.
5. We recommend three-phase sensing for applications with greatly unbalanced or highly non-linear loads.

 

MX321 AVR
1. The most sophisticated of all our AVRs combines all the features of the MX341 with, additionally, three-phase rms sensing, for improved regulation and performance.
2. Over voltage protection is built-in and short circuit current level adjustments is an optional facility.

 

Brushless Alternator 100kVA for Diesel Engine

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
1. The insulation system is class 'H'.
2. 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
1. Generators are manufactured using production procedures having a quality assurance level to BS EN ISO 9001.
2. 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%.

 

DE RATES
1. All values tabulated on page 8 are subject to the following reductions
2. 5% when air inlet filters are fitted.
3. 3% for every 500 metres by which the operating altitude exceeds 1000 metres above mean sea level.
4. 3% for every 5°C by which the operational ambient temperature exceeds 40°C.
5. Requirement for operating in an ambient exceeding 60°C must be referred to the factory.
