Transformer Principles and Applications

Front

A transformer is:

Back

A device that transfers electrical energy between circuits

Front

Is the primary side always the high voltage side?

Back

No, the primary side is not always the high voltage side.

Front

What is a bayonet fuse?

Back

An internal fuse in a pad mounted transformer.

Front

What does kVA mean and how is it used?

Back

kVA stands for kilovolt-amperes and is used to measure apparent power in an electrical circuit.

Front

What are the differences between conventional and CSP transformers?

Back

CSP transformers have built-in protection features, while conventional transformers do not.

Front

What is the purpose of a transformer core?

Back

To provide a path for magnetic flux

Front

The purpose of the insulating fluid is to:

Back

Provide electrical insulation

Front

How does the principle of convection keep a transformer from overheating?

Back

By enabling the circulation of coolant to dissipate heat.

Front

The purpose of a pressure relief valve is to:

Back

Release excess pressure to prevent system failure

How does induction work within a transformer?

Back

By using a magnetic field to transfer energy between coils
