VOLTAGE REGULATION Maintains voltage output to within + 1.5% or + 1% at any pf between 0.8 lagging and unity, at any variations from no load to full load, cold to hot and including speed droop variations at 4.5% Voltage trimmer on AVR for adjustment. Waveform Total harmonic distortion open circuit voltage waveform in the order of 1.5% Three-phase balanced load in the order of 3.5% Telephone interference TIF better than 50 THF to BS4999 Part 40 better than 2% Radio interference Suppression to BS800 and VDE class G and N. Motor starting Will withstand a short-term overload between 200% to 300% full load impedance depending on frame size and AVR used. Voltage surges Surge suppressor fitted protecting exciter rectifier against short circuits or out of phase paralleling Frequency regulation +0.25% steady state load. Unbalanced loads Optional three-phase sensing unit recommended for use with AVR if application is likely to have greatly unbalanced loads or highly non-linear loads.
