ELECTRICAL CHARACTERISTICS:
Insulation is obtained with H class materials. Impregnation: VPI. Enamel cooper wire: 200?C. Voltage is adjusted by means of an electronic regulator, fed by special winding, isolated from the main one, which proteets the regulator from overvoltage from outside. 2/3 pitch windings: avoids excessive neutral currents and ensures low waveform distortion.
Voltage Accuracy: From no load to full, cos 0,8: at constant revolving speed is ? 0,5%.
Capacity of starting the synchronous motors: 1 HP for each kVA of the alternator.
Transient Voltage Dip: Below 18% when applying the full load at cos 0.8.
Single - Phase Running: Power equal to 0.65 times the three phase power stated on the name-plate.
Frequency: 50 ? 60 HZ.
Voltages: Standard Alternators are equipped with a main winding with 12 terminals, star with neutral connection. Special voltages available on request.
Manual Voltage Adjustment: ? 5% of the nominal value. It is possible to use an external reostat for remote control adjustment.
Waveform: The waveform of the line voltage at no load and applying a balanced linear three phase load is sinusolidal with a harmonic residual less than 4%. Lower values can be obtained on request.
Radio Interferences: Normally of G degree according to VDE 0875 standard, N and K degree available on request.
Telephone Interferences: THF better than 2% (BS 4999). TIF better than 50 (ASA C 50. 12).
