Answer
# 2
Classification of alternators-
1) Salient pole(Having no of poles above 4)
2) Cylindrical (Having no of poles 2 or 4)

On the basis of cooling-
1)TARI- Turbo gen air cooled with rotor indirect cooling
2)THRI- Turbo gen H2 cooled with rotor indirect cooling
3)THW- Turbo gen H2 cooled rotor & water cooled stator
 
Is This Answer Correct ?    40 Yes 11 No

Answer
# 6
Alternators can be classified as below
Based on rotor
1. Salient pole type
2. Smooth cylindrical type
Based on output power
1. Single Phase
2. Three Phase
Based on the working principle
1. Revolving armature type
2. Revolving field type
Based on the speed on rotation
1. Turbo alternator
2. Low speed alternator
Based on coiling
1. Air cooling
2. Hydrogen cooling
 
Is This Answer Correct ?    2 Yes 0 No

Answer
# 7
alternator is divided in two parts.
1-a.c alternator.
2-d.c alternator.
a.c alternator has divided into two parts.
1-self excited.
2-separate excited.
d.c alternator has divided into four parts.
1-series
2-shunt
3-shunt compound
4-compound shunt
 
Is This Answer Correct ?    2 Yes 0 No

Answer
# 8
why all r so confuse .......

only two type r there ..........

salient pole {revolving field type} { used upto 1000 MVA}
smooth cylindrical {revolving armature type}(used upto 4 MVA)
 
Is This Answer Correct ?    3 Yes 4 No
