Electrical Transformer Symbols
Single Line Representation
The electrical transformer is a component consisting of two or more coils coupled by magnetic induction. It is used to transfer electrical energy, and to increase or decrease the tension in an AC circuit, keeping the frequency.
The autotransformer has only one winding.
