Product Description

AC Generator 20kVA 16kW 50Hz 1500RPM Three Phase for Industrial

SPECIFICATIONS & OPTIONS

STANDARDS
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 REGULATOR
AS480 AVR fitted as STANDARD
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. The AS480 will support limited accessories, RFI suppession remote voltage trimmer and for the P1 range only a 'droop' Current Transformer (CT) to permit parallel operation with other ac generators.
3. The AVR is can be fitted to either side of the generator in its own housing in the non-drive end bracket.

 

Excitation Boost System (EBS) (OPTIONAL)
1. The EBS is a single, self-contained unit, attached to the non-drive end of the generator.
2. The EBS unit consists of the Excitation Boost Controller (EBC) and an Excitation Boost Generator (EBG). Under fault conditions, or when the generator is subjected to a large impact load such as a motor starting, the generator voltage will drop. The EBC senses the drop in voltage and engages the output power of the EBG. This additional power feeds the generator’s excitation system, supporting the load until breaker discrimination can remove the fault or enable the generator to pick up a motor and drive the voltage recovery.

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 at the non-drive end of the generator. Dedicated single phase generators are also available. A sheet steel terminal box contains provides ample space for the customers' wiring and gland arrangements. Alternative terminal boxes are available for customers who want to fit additional components in the terminal box.

 

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 9 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.

 

5% For reverse rotation
(Standard rotation CW when viewed from DE)
