the generator panel.
The brushless alternator coupled with the diesel engine and installed onto
a common bed.
The alternator provided the following characteristics.
3.1 Particulars of the Alternator
(1) Standard specification
Manufacturer : NEWAGE INTERNATIONAL
Type : Brushless, self excited, self ventilating and
Protection : IP22
Power factor : 0.8 lagging
No. of pole : 4 pole
Insulation : Class “H”
Exciter : Brushless
Bearing : Single ball bearing
3.2 Characteristics (Alternator)
(1) Steady state voltage regulation
Voltage Regulation will be ± 1.0% when the load
varies between no load and full load at power factors between 0.8 and
1.0 over a prime mover speed range of 4%.
(2) Transient Response
The Instantaneous Voltage Regulation will be within 25% and recoverable to
within 3%of the final steady-state voltage in not more than 1sec., when full
load at a power factor of 0.4 or less is suddenly applied to the Alternator
running at no load and rated frequency. However engine response may
influence on recovery time.
(3) Voltage wave form
The wave form deviation of phase to phase voltage, as checked at the
alternator terminals, is not greater than 5% at no-load rated voltage.
(4) Unbalanced loading
An acceptable value of negative phase sequence current is approximately 8%
of rated current. Up to 25% load imbalance can be tolerated on a continuous
(5) Temperature rise limits
The main windings of the Alternator are designed for operation to Class H
temperature rise limits.
(6) Insulation strength
The dielectric strength of the winding insulation system is checked during
manufacture by conducting a High Voltage withstand test.
The test voltage is AC and applied at 50Hz.
Main Stator winding : 2000V
Main Rotor winding : 1500V
The Alternator is capable of withstanding overspeeds to 125% of the rated
speed for two minutes under no load.
(8) Voltage adjustment is typically ± 6% using a remotely connected trimmer.
(9) Terminal box
The large fabricated sheet steel terminal box mounted on the alternator
accommodates load output terminals and access cover.
Automatic start engine management and instrumentation system module
in fabricated cubicle is installed on individual bracket with
