Understanding Transformers

What is the primary function of a transformer in electrical systems?

• To store electrical energy

• To generate electricity

• To increase or decrease voltage levels

• To convert AC to DC

How are three-phase transformers typically connected?

• In a star configuration

• In a Y or Delta configuration

• In a parallel configuration

• In a series configuration

What is the purpose of taps in a transformer?

• To allow different output voltages

• To improve the cooling of the transformer

• To increase the efficiency of the transformer

• To reduce the size of the transformer

What should be checked when troubleshooting a transformer?

• The color of the wires

• The weight of the transformer

• Open circuits and short circuits

• The age of the transformer

When selecting a transformer, what is the purpose of using specification sheets?

• To determine the color of the transformer
