What is a Transformer?

A static device used to transfer energy from Alternating Current device to another

How does a transformer work?

• transfer energy from
  one alternating current circuit to another.

• Transfer may involve an isolation of, an

  increase or a decrease in voltage, but,

  FREQUENCY WILL REMAIN THE SAME.

Does a transformer have any moving parts?

• No

What are the 3 elements of a Transformer

• Primary Side

• Core

• Secondary Side

What are 3 classifications of Transformers

• Isolations Transformer

• Auto Transformer

• Current Transformer

What does a step down transformer do?

• Reduces the power from a higher voltage to a Lower Voltage

What does a Step Up Transformer do

Increase a lower power to a higher power

What determines the amount of Flux in a transformer winding

• Number of turns

• Size of the conductor

Describe the windings of a transformer with Low Flux

• Fewer turns

• Small Conductor

Describe the windings of a transformer with High Flux

• Many turns

• Larger Conductor

How is one Volt produced?

• One turn of wire must Cut through one Line of flux in one second

What is the Formula for to produce voltage

• E = фN/t

• E = induced voltage

  Ф = flux in webers

  N = number of turns

  t = time in seconds

What causes Copper losses

• Copper Loses are due to energy used to create a Magnetic Field

If the Primary and secondary cores do not touch, How are they Connected?

• Magnetic Flux links the coils

What else can effect the flux?

• Type of core

Whats increases the Reluctance in the Core

• reduced cross sectionals area

• Increased length of the core
