AC Generators

Product Details

Keeping in mind the precise demands of clients, we offer a wide range of AC Generators. Advanced European technology and latest equipments are used in designing these generators. A wide network of service centres add to their appeal. Electric Features include: Insulation of 'F/H' class material for both Stator & Rotor Tropicalized Windings Low-loss lamination used Voltage adjusted by an electronic regulator/compounding transformer Mechanical features include: Steel casing with end side covers in cast iron Shaft is of high-tensile C40 steel Rotor is of laminated steel (with salient poles for a better waveform) to keep sturdy while holding runaway speed of drive motors Rotor equipped with damping cage to allow satisfactory operation even in single-phase, distorted loads. Bearings with life-long lubrication up to size 631 Self-ventilation enabled through a fan fitted onto the shaft Degree of Protection: IP 23 Operating Conditions: Performance date reported in catalogue valid for operations at Altitude not exceeding 1000 m ASL Ambient temperature not exceeding 40°C Asynchronous Motor Start: 1 HP for each kVA of alternator can be started Short Circuit current: In 3-phase symmetric short circuit, the permanent current exceeds rated current by 300%, ensuring correct operation of protection Overloads: 10% overload for 1 hour every 6 hours is normally accepted Short overloads can be very high (3 times the rated current) Recovery Time: At full load, voltage returns to nominal value in less than 0.1 seconds Radio Interference: Standard units meet EN50081-1 and EN50082-1 standards. Upon request, filters can be studied & produced according to more restrictive specifications Operating at Slow Speed: Self-regulation of Brush less alternators allows slow speed operations without danger of undergoing damages Terminal Board & Terminal Box: Terminal box is of sheet steel & contains main terminals board & automatic voltage regulator/compounding transformer. Dimensions of terminal box allow easy access for connecting terminals on terminal board. A lateral opening allows access to potentiometer on regulator and set the voltage without opening the terminals box Single Phase Duty: Single-phase output power is approximately 40% of 3-phase rated power in star connections (using phase voltage) or 65% of 3-phase rated power in delta connections Output Voltage Waveform: Waveform of no-load line voltage or applying a balanced linear 3-phase load is sinusoidal with harmonical residual less than 5% Voltage Accuracy: Voltage accuracy in static conditions is within ±1% (with AVR) or within ±5% (with compounding transformer) Transient Voltage Drop: At full load, the transient voltage drop is less than 10%
