FARADAY Alternators have been carefully selected to mach the overload performance of the engine and incorporate. The following: screen protected and drip-proof, self exciting, self regulating brushless alternator with fully interconnected damper windings. ICO6 cooling system and sealed-for-life bearings. 12 reconnection windings provide a wide range of 3 phase voltages.
Automatic Voltage Regulator
The full sealed automatic voltage regulator maintains the voltage within the limit of +/- 1.5% from no load to full load including cold to hot variations at any power factor between 0.8 lagging and unity and inclusive of speed variation of 4.0%. Nominal adjustment is by means of a trimmer incorporated in the AVR.
Insulation
The insulation system is class H. All windings are impregnated in either triple dip thermo-setting moisture, oil and acid resisting polyester varnish or vacuum pressure impregnated with a special polyester resin. Heavy coat of anti-tracking varnish for additional protection against moisture or condensation.
Electrical Characteristics
Electrical design in accordance with BS5000 Part 99, IEC34-1, VDEO530, UTE5100, NEMA MG-122, CEMA 22.2 and AS1359
