  1. Alternator

 

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
rotating field

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

basis.

 

(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

 

(7) Overspeed

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.

 

4.GENERATOR CONTROL
