Class H insulation
Impregnation: VPI (vacuum and pressure).
Enamelled wires 200 degrees.
The voltage is automatically adjusted by an electronic regulator fed by a special winding, isolated from the main, which protects it from service surges.
Windings with 2/3 shortened pitch that guarantee low harmonic distortion and parallel operation with reduced neutral currents.
- Voltage Accuracy: From no load to full load, cos fi 0.8: ± 0.5% for constant speed.
- Engine Starting Capacity: 1 HP for each kVA of the alternator.
- Transient Voltage Dip: Less than 18% when the full load is applied to cosine fi 0.8.
- Single phase load: Up to a power equal to 0.65 of the normal three-phase catalog.
- Frequencies: 50 or 60 Hz.
- Voltages: Alternators are normally supplied to 12 star terminals with accessible neutral. Special voltages upon request.
- Manual Voltage Adjustment: ± 5% of the nominal value. An external rheostat can be connected to do it remotely.
- Waveform: Total Harmonic distortion less than 4% for L-N voltages with no load or three phase balanced linear loads.
- Radio Interferences: Normally they are G grade according to VDE 0875 standards. Grades N and K, on request.
- Telephone Interferences: THF lower than 2% (BS 4999). Lower TIF 50 (ASA C 50.12).
- Short Circuit Current: Greater than 3 times the nominal.
- Parallel Device: G2R 250 and larger are provided with AVR prepared for parallel operation with other alternators of the same or different brand.Bellow G2R 250, on request.
- Ratings: The values on the rating charts refer to the following conditions: maximum ambient temperature 40 ° C, Altitude no over 1000 m a.s. and cos fi 0.8.
OPERATION UNDER SPECIAL CONDITIONS
At an altitude higher than 1000 m.s. Is necesary a power derate of 4% every 500 m of increase.
At room temperature greater than 40 ° C, it is necessary to derate the power 4% every 5 degrees of increase.
Overloads: 10% overload for 1 hour every 6 hours. Larger overloads can be accepted for short times. (2.5 times the rated current).
