Practice # 8 AC & DC Generation

Front

What completes the magnetic circuit between the poles in a DC generator?

Back

Field frame.

Front

What is a DC generator with a field winding connected in parallel with the external circuit called?

Back

Shunt generator.

Front

What does a voltage regulator adjust in a DC generator?

Back

The voltage output by altering the amount of current flowing to the generator's field windings.

Front

What components make up the armature assembly of a generator?

Back

Many armature coils wound on an iron core, a commutator, and associated mechanical parts.

Front

What additional component does a three unit regulator for DC generator systems include besides a voltage regulator?

Back

Current limiter.

Front

What is the primary function of the field frame in a DC generator?

Back

To complete the magnetic circuit and provide mechanical support.

Front

How does a shunt generator differ from other types of DC generators?

Back

It has a field winding connected in parallel with the load.

Front

What role do field windings play in a DC generator?

Back

They create the magnetic field necessary for generating electricity.

Front

What is the purpose of a commutator in a DC generator?

Back

To convert alternating current (AC) generated in the armature to direct current (DC).

Front

What is the significance of a reverse current cutout in a DC generator system?

Back

It prevents reverse current flow that could damage the generator.
