The Practical Tx

The core of a transformer (Tx) is laminated and insulated from one another to....

• reduce hysteresis loss

• reduce magnetic leakage

• reduce eddy current loss

• reduce construction costs

The laminations are prevented from shorting together by....

• placing a layer of insulation between each lamination

• filling the transformer with insulating oil

• spacing the lamination apart

• applying a varnish or oxide layer on each lamination

Transformer cores are manufactured from what type of material?

• Mild steel

• Iron

• High Grade Silicon Steel
