Generator is the most important device in electric field,generators are classified based on application.

GENERATORS

1. AC GENERATORS or ALTERNATORS (which have frequency).

      1.SYNCHRONOUS GENERATORS (having constant frequency)

                      1.ARMATURE ROTATING.

                      2.FIELD ROTATING.

      2.ASYNCHRONOUS GENERATORS (INDUCTION GENERATORS, variable frequency)

2. DC GENERATORS (zero frequency)                        

      1.SHUNT GENERATORS.

      2.SERIES GENERATORS.

      3.COMPOUND GENERATORS.                

at factory so many tests are going to do by manufacture

DIFFERENT TESTS are to be done at field :

1.MEGGER

2.WINDING RESISTANCE
